Catfishing is the intentional use of a false online identity to deceive someone. It is often under the pretense of an emotional or romantic relationship and for the purpose of engaging someone in an activity. While the concept of catfishing is often associated with adults’ experiences of online identity deception, it is increasingly becoming a part of young people’s online experiences of humiliation and bullying, sexual exploitation and image-based sexual abuse. In this presentation, we will discuss findings from a study of 1, 953 adolescents in Australia, including overall prevalence of catfishing, patterns of victimization and negative impacts, and perpetrator profiles. The study also asked adolescents their views towards catfishing to gain insight into their perceptions of its normalization and harms. Finally, the presentation offers critical insights for policy and practice regarding adolescents, technology and the prevention of online sexual exploitation of children.
