Who Is Bob_34? sheds light on the clandestine world of online child pornography and pedophilia. What exactly do we know about these crimes? Who produces child cyberpornography? Who distributes it? Who consumes it? And is there a link between viewing and abuse? By infiltrating child-porn user groups and comparing their findings to scholarship on the topic, Francis Fortin and Patrice Corriveau address these questions and more, opening a window on a world that is much more complex than media accounts and commissioned reports suggest.
