“…Even without explicit calls for harassment, we argue that response videos create conditions in which harassment flourishes-a blueprint for harassment. If perpetrators of harassment often believe that their actions are justified (Blackwell, Chen, Schoenebeck, & Lampe, 2018;Jhaver, Chan, & Bruckman, 2018), and if harassment is understood as punishment for norm violation (Crockett, 2017;Hill & Johnson, 2020), then these videos draw upon social norms shared by a networked audience and the technical affordances of YouTube to explain to the audience not only why the target is wrong, but why they are immoral and why harassing them would be justified.…”
