A systematic review of the literature collects and categorizes various studies (Williams, 2019) and answers specific questions by addressing connections between these studies (Baumeister & Leary, 1997). The studies included in this article reflect the influences of SNS use on cybercrime victimization. Therefore, search terms were actual words of the given topic, divided into two dimensions: (1) search terms for communication technology and victimization in cyberspace and (2) general terms and specific terms. Based on search terms from other review articles on SNS (Chen et al., 2023; Newman et al., 2021; Rus & Tiemensma, 2017; Saiphoo et al., 2020) and cybercrime victimization (Ho & Luong, 2022) as well as the synthesis of keywords in the research on cybercrime victimization from 2010 to 2020 (Ho & Luong, 2022), the current article selected several of the most used keywords. More details are provided in Figure 1.

Groups of Search Terms

Keywords were combined to search using the appropriate Boolean terms. Search terms were applied to databases of Scopus, Web of Science – Social Science Citation Index (WoS-SSCI), and Web of Science – Science Citation Index-Expanded (WoS-SCIE). These databases are the central search system for conducting a systematic literature review (Gusenbauer & Haddaway, 2020; Zyoud et al., 2018).

Four main inclusion criteria were applied according to the topic, objectives, and scope of this investigation. First, all journal articles were in English since most of the research indexed in selected databases is compiled in this language. Second, the studies must be empirical and quantitative; variables of SNS use and cybercrime victimization were measured by the respondents’ self-report because the current research plans to observe the relations between these variables. Third, the construct of SNS use can include various elements concerning SNS, such as frequency of use, behaviors on SNS, and characteristics of SNS or SNS users; the construct of cybercrime victimization could be related to experience, susceptibility, or risks of cybercrime victimization. Fourth, the selected studies must address how SNS use, as the independent variable, impacts cybercrime victimization as the dependent variable.

Furthermore, excluded papers are identified according to several criteria: (1) not journal articles and not written in English; (2) not empirical research, qualitative research, no inferential statistics; (3) investigate the perspective of ICT, the Internet, social media or SNS use but have no the variable of cybercrime victimization; (4) focus on the perspective of cybercrime victimization but lack elements of SNS use (the general Internet or social media use were not accepted) or SNS use is not examined as an affecting factor; (5) other perspectives of cybercrimes beyond victimization (i.e. legal issues, offenders, or policies); and (6) other cases which are irrelevant to studied topic.

PRISMA - Preferred Reporting Items for Systematic Reviews and Meta-Analyses (Moher et al., 2009) were used for collecting data because it provides a straightforward and suitable procedure for review research, with more details presented in Figure 2. The selected keywords were retrieved from Scopus and WoS in January 2023. The data files were exported automatically; the initial result included 1833 documents (998 Scopus papers and 835 WoS-SSCI and WoS-SCIE papers). This study used R Studio to merge data files from two databases and remove 377 duplicates. In the Excel file, by filtering in the column of language and document types, 449 documents were released due to the exclusion of criterion one (not in English, review articles, book chapters, notes, letter, conference review, conference paper, proceeding paper, corrections, and editorial materials).

The PRISMA Diagram Depicts Data Collections

Then, 1007 papers were selected by title and abstract. First, an author wrote a draft classifying the screened articles, including three groups: 1) eligible articles were highlighted in yellow, 2) excluded articles were highlighted in red, and 3) papers that needed more consideration were highlighted in gray. The excluded articles were divided into subgroups according to the exclusion criteria. Then, based on the draft, the authors worked together to discuss and make the final decision for each article.

As a result, 966 studies were excluded. Specifically, 259 articles were removed due to the second exclusion of criterion 2. Numerous articles were qualitative research, systematic review, comparative study, measurement development, applied case study, discourse analysis, content analysis, deep learning, or machine learning. One hundred and sixty-seven articles were removed due to the third exclusion criterion (examined the use of social networks, the Internet, online dating sites, and gaming sites without variables of cybercrime victimization). A plethora of studies focused on the consequences of cybercrime victimization or factors that affect other factors, except SNS use (358 articles) were removed based on the fourth exclusion criterion. Some studies addressed the relationship between the general use of the Internet or social networks and victimization by cybercrimes, but they were also removed. The current research targeted SNSs due to the different attributes of SNSs compared to other types of ICT. Furthermore, according to the fifth exclusion criterion, 138 articles related to the prevalence of cybercrime, offenders, intervention, prevention, or detection of cybercrimes were removed. Due to exclusion criterion six, 44 cases aimed at exploring traditional crime, issues of law and policies, or psychological issues were unsuitable for the current study.

41 articles were reviewed in full text, and 17 were removed after review and discussion among the authors. Although these studies covered both elements of SNS use and cybercrime victimization, they did not indicate the influence of the former on the latter or applied descriptive analysis only. The final eligible articles were 24.

The current study uses content analysis to explore the given topic because this analytical approach is suitable for text data and supporting interpretation from systematic data synthesis (Krippendorff, 1989). Quantitative and qualitative analysis is combined to describe the status of applied theories and types of cybercrime and interpret the influences of SNS use on cybercrime victimization.

To provide answers to the research questions and in the hope that we would be able to move beyond the basic details of the studies that were examined, such as titles, authors, years of publication, and overall objectives, we designed this study to synthesize the data into four distinct categories, including 1) employed theories, 2) examined cybercrimes, 3) main independent variables, and 4) key findings. Data from categories one and two are for the first research question; the others were used for the second and third questions.

Applied Theories. Half of the reviewed research was theory-driven (12 out of 24 studies); the others did not apply a specific theory but were based on the relevant literature for theoretical frameworks. The most frequently employed theory was Routine Activity Theory (RAT, seven out of 12 theory-driven studies)

RAT (Cohen & Felson, 1979) was originally used to explain traditional crime victimization and then widely applied to cybercrime victimization (Kirwan et al., 2018). Three core components of RAT are (1) motivated offenders, (2) suitable targets, and (3) the absence of capable guardianship. According to RAT, the victimization event was the result of the spatiotemporal convergence of motivated offenders and suitable targets without capable guardianship. A motivated offender refers to a person who has the capacity and motivation to commit a crime and is seeking prey (i.e. scammers, hackers, stalkers; Nguyen, 2020). This component is often examined as ‘exposure to motivated offender’, which is the accessibility of victims to potential offenders. Suitable targets are various from a person or an organization to confidential data, online payment, online services, or computer systems that may be opportunistic or targeted selection due to certain attributes and circumstances. Unlike traditional crime, spatiotemporal convergence is not necessary for cybercrimes to occur because the offenders and victims may be online at different times and a long physical distance. Capable guardianship includes factors that protect potential victims from victimization. Given the context of cybercrime, guardianships can be in numerous forms ranging from human factors (i.e. online administrators, online peers, parents) to non-human factors (i.e. anti-virus software, firewalls, passwords, two-step verification; Leukfeldt & Yar, 2016).

Several studies comprehensively examined all three components (Bossler et al., 2012; Navarro et al., 2017; Räsänen et al., 2016; Saridakis et al., 2016; Welsh & Lavoie, 2012) while the others investigated one or two components (Kirwan et al., 2018; Mesch, 2018).

It is believed that the greater the exposure to potential offenders, the greater the victimization of cybercrime (Bossler et al., 2012; Navarro et al., 2017; Räsänen et al., 2016; Saridakis et al., 2016; Welsh & Lavoie, 2012). Some constructs used to measure the first component included the frequency of SNS use (Bossler et al., 2012; Kirwan et al., 2018; Mesch, 2018; Navarro et al., 2017; Saridakis et al., 2016; Welsh & Lavoie, 2012), years of SNS use (Kirwan et al., 2018), number of devices for SNS use (Kirwan et al., 2018), number of SNS accounts (Bossler et al., 2012), number of friends on SNSs (Räsänen et al., 2016), public profile on SNSs (Mesch, 2018), lying about age (Mesch, 2018), sharing a password (Mesch, 2018), activities on SNSs (i.e. commenting on friends' posts, sending private messages, tagging people in posts, updating statuses, posting video or photo, playing games on SNS; Mesch, 2018), online peer harassment (Bossler et al., 2012), and engaging in online deviance or offending (Bossler et al., 2012; Räsänen et al., 2016). Factors such as spent time, number of devices, number of friends, or online activities were supposed to increase the presence of users in cyberspace; hence, they also increased the exposure to offenders. Even though some constructs of the first component may cause confusion and should be better examined as measures of the second component (i.e. lying about age, sharing a password, or some specific online activities). The last two factors were included in the first component because participation in online deviance or connections with peers harassing others on SNSs put users into a larger community of offenders and deviants.

Relating to the suitable target component, previous research often examined personal factors such as risk-taking behaviors on SNSs (Saridakis et al., 2016; Welsh & Lavoie, 2012), low-risk perception (Saridakis et al., 2016), concerns about potential cybercrime victimization (Räsänen et al., 2016), prior negative offline experience (Räsänen et al., 2016), and demographic attributes of users (Bossler et al., 2012). Furthermore, the factor of activities on SNS (Navarro et al., 2017; Räsänen et al., 2016) and participation in online offending (Navarro et al., 2017) were also examined given the second component in several research works. These factors not only increased the online presence of users, leading to exposure to potential cybercriminals but could also be considered the characteristics of individuals that made them suitable targets for cybercrimes.

Regarding the last component, guardianships were supposed to decrease cybercrime victimization. Measures of guardianship can be categorized as (1) physical guardianship, hardening a target from victimization; (2) social guardianship, the presence of individuals with the capacity to deter attacks or offer safeguard from crimes; and (3) personal guardianship, individuals’ characteristics that protect them from crimes (Bossler et al., 2012). In previous research, physical guardianship included protective software programs (Bossler et al., 2012) and the location of using (Bossler et al., 2012). It was supposed that it was easier to control someone’s online activities in the common area than in the private area to limit risky activities. Social guardianship focused on parental control (Mesch, 2018; Navarro et al., 2017; Räsänen et al., 2016), the connection of parent and child on SNSs (Mesch, 2018), and less peer computer deviance (Bossler et al., 2012). Personal guardianship consisted of information control (Saridakis et al., 2016), computer skills (Bossler et al., 2012; Saridakis et al., 2016), and less risky information sharing (Bossler et al., 2012; Welsh & Lavoie, 2012). Two variables ‘peer computer deviance’ and ‘risky information sharing’ were employed to measure the guardianship because Bossler et al. believed that the less peer computer deviance and sensitive information sharing, the more guardianship. However, these two variables were also used for the first and second components, respectively, in some different research, so it might create confusion somehow.

Several variables were used flexibly for more than one component of RAT in the different studies. For example, SNS activities and online offending were examined as the component of exposure to potential offenders (Mesch, 2018) and the component of target suitability (Navarro et al., 2017). It depended on the decisions of the researchers to categorize a construct into which component because each construct can be interpreted in several different directions. The phenomenon of overlap exists mainly in different research. Furthermore, it is noted that it often appeared when one work covered three components and the other examined one or two components only. In a special case, peer deviance was used to measure both the component of exposure to offenders and guardianships in the same research (Bossler et al., 2012). Bossler et al. recognized the complexity of the overlap, but they still categorized peer harassment as a variable of the first component and peer computer deviance as a measure of the third component. Furthermore, some components of RAT were more likely to be significant than others (Leukfeldt & Yar, 2016). Specifically, variables classified as exposure to offenders and suitable targets were more significantly correlated with cybercrime victimization than guardianships (i.e. locations of using SNSs, protective software, and computer skills had no effect on the risk of cybercrime victimization).

Similarly to RAT, Lifestyle Exposure Theory (LET, Hindelang et al., 1978) and Lifestyle-Routine Activity Theory (LRAT, Cohen et al., 1981) are in a group of criminal opportunity theories which were employed in the context of cybercrime victimization (LRAT was applied in two studies, and LET was applied in one study). These theories have close ties (Vakhitova et al., 2016). RAT was supposed to expand LET; LRAT integrated LET and RAT. While RAT describes the event of victimization itself (the convergence of three core components results in crime victimization), LET emphasizes the risk of victimization from the probabilistic perspective (Pratt & Turanovic, 2016). LET indicated that several people are at higher risk of crime victimization than others due to their lifestyle (Vakhitova et al., 2016). The lifestyle here is a set of daily activities (Madero-Hernandez, 2019) that contain vocational and leisure activities (Hindelang et al., 1978). Meanwhile, LRAT consisted of five elements: exposure, proximity, target attractiveness, guardianship, and properties of crimes (Cohen et al., 1981). Exposure to offenders refers to the visibility or accessibility of individuals to potential offenders. Proximity to offenders refers to the physical distance between potential victims and offenders. Target attractiveness refers to “the material or symbolic desirability of persons or property target” (Cohen et al., 1981, p. 508), and levels of resistance to attack (McNeeley, 2015). In terms of guardianship, potential victims who are less well-guarded are more likely to be attacked. Last, properties of specific crimes are suggested to have close connections with possibilities for crimes and influence on four factors above. To explain victimization in cyberspace, LET and LRAT mainly asserted that online victimization was closely related to the victim’s online lifestyle (Suh et al., 2020), for example, frequency of SNS use, disclosure of preference on SNSs, expression of opinions or feelings on SNSs, extensity and intensity of SNS use and risky lifestyle on SNSs.

LET, RAT and LRAT originally were applicable for traditional crimes (with direct contact between offenders and targets). LET just examines the risky factors increasing the probability of victimization while RAT and LRAT investigate the convergence of factors leading to the event of cybercrime victimization. It seems that LRAT comprehensively examines crime victimization through more elements than the others. However, given an online environment, the physical distance is blurred, and then the construct of proximity to offenders did not maintain the original meaning and was used interchangeably with exposure to offenders in some research (Bossler et al., 2012). Furthermore, it is difficult to examine the role of properties of a specific cybercrime in cybercrime victimization from the victim survey research. Previous research using LRAT often examined only three factors similar to RAT. Then, RAT was the most applied theory.

However, not all components of these theories had significant associations with cybercrime victimization. Some findings did not completely support the effectiveness of these theories (Navarro et al., 2017). Therefore, evaluating their value appeared challenging (Leukfeldt & Yar, 2016), leading to an argument about the usability of these theories in explaining cybercrimes. Furthermore, RAT, LET, and LRAT seemed suitable for “single entities” (van der Wagen & Pieters, 2020, p. 7) but not for “a chain or network of various human, technical, and/or virtual elements” (van der Wagen & Pieters, 2020, p. 7).

Despite the controversies, LET, RAT and LRAT are still critical theories for investigating victimization in both physical and virtual worlds. There is a lack of sufficient evidence to reject RAT, LET, and LRAT (Räsänen et al., 2016). These theories also demonstrated their benefits in explaining specific types of cybercrime victimization. The nature of each cybercrime and the characteristics of sample populations are different, so the usability of these theories can vary (Leukfeldt & Yar, 2016). Cybercrime was divided into two main categories, including cyber-enabled crimes (i.e. cyberfraud) and cyber-dependent crimes (i.e. hacking). The former usually involves more victim-related factors than the latter; meanwhile, the latter more involves technology than the former. It was obvious that RAT, LET and LRAT were likely to examine cybercrime from the perspective of human beings. As a result, their applications for cyber-enabled offenses, such as cyberbullying, were given preference. Furthermore, the result may be different in the alternative samples. For example, the frequency of SNS use was indicated to increase online victimization in the sample of adolescents or young people (Kokkinos & Saripanidis, 2017; Mesch, 2018; Miguel et al., 2020; Navarro et al., 2017; Peluchette et al., 2015) but no significant effect within the sample at the age of 10 to 59 (Suh et al., 2020). Another reason might be due to the restrictions of methods such as small non-representative samples in several research (Leukfeldt & Yar, 2016).

Beyond RAT, LET, and LRAT, other theories employed were the Theory of Reasoned Action (TRA, Fishbein & Ajzen, 1975), the Theory of Planned Behaviors (TPB, Ajzen, 1985, 1991), the Social Tie Theory (STT) or Social Network Theory (SNT, Granovetter, 1973), and the Source Credibility Theory (SCT, Hovland & Weiss, 1951; Hovland et al., 1953). TPB was considered an advanced version of TRA. TRA indicated the relationships between attitudes, subjective norms, behavioral intention, and behavior. Beyond these factors, TPB included another factor, namely perceived behavioral control. In the literature, TRA and TPB were applied to account for SNS behaviors, and how SNS users decided to respond to an online request and became victims of cybercrimes on SNS (Saridakis et al., 2016). STT or SNT focuses on the construct of social ties or social networks that are a set of relationships between two or more individuals. Social ties may be categorized as strong or weak social ties. The strengths of social bonds were believed to play a protective role in both physical and virtual environments. Therefore, previous research evaluated the impact of social connection strength on cybercrime victimization (Keipi et al., 2017). Lastly, source credibility is a term that covers the positive characteristics of information or communication sources that impact the acceptance of information receivers of information (Ohanian, 1990). Source credibility theory asserted that receivers had the likelihood to believe and accept a message from a source that seemed to be credible (Hovland & Weiss, 1951). Therefore, this theory was used to investigate the effect of the credibility of the source on user behaviors and their risks of victimization online (Algarni et al., 2017).

While several different theories were examined, the quantity was modest because these theories did not aim to directly explain victimization as RAT, LET, or LRAT did. Instead, these theories cover some constructs that can affect victimization or explain victim behavior.

Types of Cybercrime. The reviewed studies concern a variety of cybercrimes, as shown in Table 1. Consistent with previous results, reviewed research focused mainly on cyber-enabled crimes, and cyberbullying was the most common cybercrime (50% of the total published articles), followed by cyberstalking and online harassment (33.3%), cyberscams such as phishing or romance scam (20.8%), online hate or offensive content (16.7%), and cyber impersonation and identity theft (12.5%). Some other cybercrimes, such as hacking (8.33%), online sexual solicitation on SNS (8.33%), or spam (4.16%) were scarcely documented. Except for cyberbullying, other cybercrimes were investigated less separately. Instead, they were measured as items for cybercrime victimization. For example, Saridakis et al. (2016) measured cybercrime victimization through several items including victimization of spam, online fraud, offensive content and online harassment; Suh et al. (2020) included some items relating to cyber harassment, cyber impersonation and cyber hacking in the variable of cybercrime victimization.

Given that RAT and LRAT, the most common theories in previous studies, are suitable for cyber-enabled crimes and individual cases, it is understandable why cyberbullying was the most frequently examined. Furthermore, the rise of the Internet and SNS increases the risks of rapidly distributing toxic messages and images (Choi & Lee, 2017). There are numerous opportunities for cyberbullying or harassment to become prevalent, appealing to the concerns of scholars. These types of cybercrime seem to be a decidedly special issue among children and youth (Aizenkot, 2020; Navarro et al., 2017), the most frequent population in research.

The retrieved studies examined various variables which were categorized into two main groups: The first group was related to SNS experience (i.e. general use and activities on SNS), and the second group was related to the characteristics of users (psychological, social, and demographic attributes).

Variables of the SNS Experience. A wide range of research concerned factors regarding general SNS use such as the number of SNS accounts, frequency of use (years of SNS use or time spent on SNS), devices for SNS access, locations of use, mutual friends, recognition of friend requesters, SNS habit strength, deficient self-regulation, and privacy setting or self-disclosure (i.e. keep personal information including real name, facial photo, address, gender, age, phone number, email address in public or private setting). Of these variables, several were the most used in the studies, containing time spent, number of friends on SNS, number of SNS accounts and privacy settings.

Except for the variables of general use of SNS, the previous research also investigated variables of SNS activities. Numerous measured items were related to the most elementary features of SNS, such as updating profiles, posting photos or videos, adding friends, sending messages, leaving comments, tagging, posting status updates, sharing feelings, and playing games on SNSs. Besides, some risky online activities (i.e. bullying others, online offending, searching and accessing harmful content, interacting with strangers, and adding strangers as friends) were also important variables given the lens of LET, RAT, and LRAT.

Variables of SNS Users’ Characteristics. In addition to SNS experience, other factors related to SNS users were tested to understand their relationships with the likelihood of victimization by cybercrimes, including psychological, social, and demographic aspects. Psychological factors were frequently examined variables, related to perception perspectives (i.e. the perception of source credibility, including perceived sincerity, competence, attraction and worthiness of the source; Algarni et al., 2017), personality (i.e. extraversion, agreeableness, conscientiousness, neuroticism, and openness; Kirwan et al., 2018; Peluchette et al., 2015), self-esteem (Kokkinos & Saripanidis, 2017), or emotion (i.e. depression, loneliness and fear; Kokkinos & Saripanidis, 2017; Räsänen et al., 2016). Social aspects of SNS users contained previous cybercrime experience (Räsänen et al., 2016), parental control (Bossler et al., 2012; Mesch, 2018), parent-child connection (Mesch, 2018; Navarro et al., 2017), social ties (Keipi et al., 2017; Wegge et al., 2015), offline victimization (Marret & Choo, 2017; Räsänen et al., 2016), offline perpetration (Marret & Choo, 2017), online peer deviance (Bossler et al., 2012), or parent conflict (Marret & Choo, 2017). Lastly, previous research mentioned demographic attributes of SNS users, such as gender, age, or education phrase.

Generally, previous research covered numerous basic factors of SNS experiences (general use and SNS activities) and explored them from the angle of risk factors rather than safety factors (Ngo et al., 2020). Most variables were selected under the lens of the RAT components as analyzed above. In addition to factors of general use of SNS and online activities, psychological factors were crucial to understanding how online victimization occurred. Numerous cybercrimes require certain levels of involvement; then, users’ decision-making may open up more chances for cybercrime success (Ho & Luong, 2022). Furthermore, social and demographic factors provided cyber offenders with detailed descriptions of suitable targets.

There were very few variables regarding non-human factors (i.e. technological perspectives or features of social network platforms) to understand how suitable each platform is for properties of cybercrimes. The reasons may be partly due to the research method of the self-report survey and the theories applied.

The use of SNSs positively influences cybercrime victimization in several aspects. The more SNS accounts, the higher the risk of interpersonal victimization (Henson et al., 2011) because a great number of SNS accounts gave potential offenders more avenues to access potential victims (Reyns, 2010). Numerous research indicated that the number of online friends positively affected cybercrime victimization (Choi & Lee, 2017; Kokkinos & Saripanidis, 2017; Peluchette et al., 2015; Wegge et al., 2015). Besides, individuals with longer duration of SNS use (Kirwan et al., 2018) and a high amount of daily time spent on SNS were likely to be victims of cybercrimes (Kokkinos & Saripanidis, 2017; Mesch, 2018; Miguel et al., 2020; Navarro et al., 2017; Peluchette et al., 2015).

The low level of privacy setting, the public nature of personal information in SNS (real name, facial photo, address, gender, age, phone number, email address), or the disclosure of personal information in SNS increased cybercrime victimization (Aizenkot, 2020; Kokkinos and Saripanidis, 2017; Suh et al., 2020; Tsitsika et al., 2015; Welsh & Lavoie, 2012). Online self-disclosure and lower privacy settings might leak sensitive information against users and turn them into suitable targets for offenders. Personal information was easily used for impersonation, identity theft, and other online scams. Users may encounter a higher risk of cyber harassment or online hate because personal information provides harassers with various materials for their villainous behaviors (Bossler et al., 2012). Furthermore, due to the centralized nature, information exploitation, and poor privacy of numerous SNS, users need to be increasingly concerned about privacy issues on these platforms, especially after the privacy violation case of Facebook. Most of the SNSs available to date may provide opportunities to exploit user content (Poongodi et al., 2020), and user’s personal information is collected and used without permission. Therefore, information control played a role in decreasing the risk of victimization (Saridakis et al., 2016); users with high privacy concerns were less likely to be victims of cybercrimes (Vishwanath, 2015).

Hazardous SNS activities including sharing feelings on SNS (Suh et al., 2020), updating status regularly (Navarro et al., 2017), adding strangers as friends (Henson et al., 2011), submitting intimate images (Marret & Choo, 2017), interacting with strangers (Marret & Choo, 2017), online offending or online bullying (Marret & Choo, 2017), sharing inappropriate information (Kokkinos & Saripanidis, 2017), searching and accessing harmful content (Räsänen et al., 2016) had positive associations with cybercrime victimization. These activities, especially risky online activities, were supposed to increase the probability for users to expose themselves to offenders and turn them into attractive targets of attackers on SNS.

In addition to the experience of SNS, a wide range of psychological, social, and demographic attributes of SNS users were also positively associated with cybercrime victimization. Users who perceive the high credibility of SNS sources (via several characteristics of sources such as a large number of friends, using a real name for the source, mutual friends, or owned by celebrities) were easier to fall into social engineering-based attacks on Facebook. Another point is that users with high extraversion and openness were positively associated with cyberbullying victimization (Peluchette et al., 2015) and SNS scam victimization (Kirwan et al., 2018). They were more willing to adopt risky online behaviors, which positively influenced the victimization of cybercrimes. Similarly, users with low agreeability and conscientiousness increased the risk of being victimized (Kokkinos & Saripanidis, 2017). Previous studies also found that people with higher depression, loneliness, and fear of victimization were likely to fall into Facebook victimization (Kokkinos & Saripanidis, 2017; Räsänen et al., 2016). Other users’ problems, such as online and offline perpetrations, online and offline victimization, parental conflict, or peer harassment online, led to an increased rate of cybercrime victimization (Bossler et al., 2012; Marret & Choo, 2017; Räsänen et al., 2016). Several factors related to online relationships had negative associations with cybercrime victimization, such as being friends with parents on SNSs (Mesch, 2018) and the strengths of online relationships (Keipi et al., 2017). The former was indicated to mitigate the likelihood of cyberbullying victimization, and the latter reduced online hate and harassment victimization.

However, it was observed that there were some inconsistent results between different studies. There were no significant correlations between cybercrime victimization and variables related to the number of friends on SNS (Keipi et al., 2017; Räsänen et al., 2016), frequency of use (Suh et al., 2020), and parental control (Navarro et al., 2017). The reason for the differences in the results of the first two factors might be due to the different measures and coding methods in the different research. The factor of parental control was expected to be guardianship of protecting young users from cybercrimes. However, it was observed that the strengths of the relationship between parents and children were not the same within the different social-cultural communities. Hence, the inconsistent results related to parental control are understandable.

Inconsistency was also found in results for gender and age. From the perspective of gender, some findings suggested that women were more likely to become victims of cybercrime (Algarni et al., 2017; Mesch, 2018; Navarro et al., 2017; Rodríguez-Enríquez et al., 2019; Tsitsika et al., 2015) but others showed the opposite; men had higher risks of falling into cybercrime victimization (Aizenkot, 2020; Marret & Choo, 2017; Miguel et al., 2020). Several studies even indicated that gender had no association with cybercrime victimization (Kokkinos & Saripanidis, 2017; Räsänen et al., 2016). With age, young adults were more susceptible to social engineering (Algarni et al., 2017). Young people represented the largest and most active group of users on SNS (Baker & White, 2010; Subrahmanyam et al., 2008) , then their frequent presence and activities in cyberspace might increase the exposure to potential offenders and the risks of victimization according to RAT. However, most of the reviewed studies found that age had no connection with cybercrime victimization on SNS (Kokkinos & Saripanidis, 2017; Räsänen et al., 2016; Tsitsika et al., 2015).

The advantages of SNS are undeniable, and so are the drawbacks of SNS. The presence of cyberspace users or their participation in SNS activities might put them in negative experiences in various ways, especially given the lack of capable guardianships. Therefore, users are expected to fully perceive the risks of cybercrime victimization in SNSs and effectively control their attendance in cyberspace.

In addition to summarizing previous studies, the current article also aims to recommend directions for future studies. Therefore, the following subsections will discuss more directions for future research.

This review paper retrieved 24 journal articles on the influences of SNS usage on cybercrime victimization from the Scopus database, WoS-SSCI and WoS-SCIE. It synthesized applied theories, types of cybercrime, main variables, and key findings reflecting the influence of SNS use on cybercrime victimization. In most previous studies, RAT and LRAT were utilized to explore cybercrime victimization on SNSs, the focus being cyberbullying rather than other forms of cybercrime. The findings demonstrated an apparent association between SNS usage and being a victim of cybercrime in terms of the following two primary aspects: SNS experience (general use and particular activities in SNS) and SNS users’ characteristics (psychological, social, and demographic attributes). There is little doubt that using SNS increases the risk of being a victim of cybercrime, although different studies have produced contradictory findings.

This research has been determined to have some shortcomings. Only major academic databases, including Scopus, WoS-SSCI, and WoS-SCIE, were used to retrieve the articles, and the articles examined had to be published in English and use quantitative research methodologies. Consequently, there was a possibility that not all articles related to the subject presented were investigated. The sample population and primary variables were summarized in the article; however, there was no in-depth analysis of the sample or the measurement scale of the variables. To learn more about various points of view, it is recommended that further research be conducted with eligible articles retrieved from other databases, such as the International Bibliography of the Social Sciences, PsychoINFO, or Communication and Mass Media Complete. Inclusion criteria must also be expanded to examine other types of methodology, including qualitative and mixed methods, and the papers selected can also be drafted in other languages. All these limitations should be called for further consideration in the future.
