RESEARCH ARTICLE
A new peer-reviewed research article, produced as part of the EU-funded Project 2KNOW by an international multidisciplinary research team, was published in the respected journal Child Abuse & Neglect. The study investigates the differences between CSAM offenders who self-report having been charged for sexual offenses against a child or an adult and those who self-report not having been charged of such offenses.

The study analyses anonymous survey data from 2384 respondents who sought CSAM on the dark web. The sample was divided into three groups: those who admitted to having been charged for sexual offenses against children (CS offenders), those who admitted to having been charged for sexual offenses against adults (AS offenders), and those who admitted to no charges (NC group). We used multinomial logistic regression analysis to analyze differences in self-reported behavior and motivation to access CSAM between the three groups.
The research found that having charges for a violent offense against a child or an adult, searching for material depicting the sexual abuse of infants and toddlers, grooming children, and having physical contact with children significantly increased the risk of belonging to the AS or CS group compared to the group that reported no charges.
