Since their very beginning, new technologies have been used to perpetrate crimes related to child sexual abuse. Indeed, they provide for an ideal environment for the production, acquisition, possession and distribution of child sexual abuse materials, while guaranteeing anonymity to their users. Moreover, they allow individuals having a sexual attraction for children to meet, share their experience and find justifications to their deviant behaviour.

This analysis is the first part of a diptych dedicated to child sexual abuse materials on the Internet. It aims at throwing a closer look on the motives, influences and interactions between users of child sexual abuse materials and the justifications they use to minimize their behaviour.
