This research shows that toxic behavior in online games is contagious, especially from teammates. Using machine learning and econometric analysis of 300,000 messages, it finds toxicity spreads socially rather than individually. The study suggests that effective interventions should target breaking transmission patterns rather than simply punishing players to improve online environments.

This research examines sexual harassment and cyberbullying in online gaming, highlighting how women and gender-diverse players face disproportionate harm. By analysing real player disclosures and addressing the disconnect between gamer experience and research definitions, the project aims to develop accurate, community-informed prevention programs to better protect players and reduce online harassment.
