Cybersex trafficking is a widespread and escalating worldwide problem that surpasses geographical boundaries, cultural differences, and socio-economic conditions. The internet has not only increased the scope and anonymity of traffickers, but it has also made it more difficult to combat these crimes due to transactions and exchanges taking place in the hidden realms of cyberspace. In spite its ubiquity, very few studies have looked into the subject of interest in a localised lens. Thus, this study is conducted to empirically assess the influence of exposure in sex trafficking through social media platforms on the level of participation of cybersex trafficking in Cantilan, Surigao Del Sur, Philippines. The study also delved into testing the possible moderating role of self-concept on the association of the said variables. Using 337 structured survey responses from conveniently sampled individuals, the results of the study showed that a moderate level of both exposure and participation was present in the observed group. In addition, the moderation analysis further demonstrated that exposure significantly influences participation, confirming that individuals who frequently encounter suspicious profiles, unsolicited messages, and related advertisements are more likely to engage in cybersex trafficking activities. Finally, the analysis conducted also proved that self-concept significantly moderates the influence of exposure to sex trafficking through social media on the level of participation in cybersex trafficking, was also supported by the data. Thus, the interaction between exposure and self-concept was found to be significant, indicating that self-concept indeed moderates this relationship.
