Riot Games deployed an automated text evaluation system across League of Legends, VALORANT, and Wild Rift in November 2022 that uses machine learning models to assess player-reported chat messages and apply penalties such as mutes and bans for harmful, offensive, or inappropriate content.

The system uses multiple machine learning models to classify in-game chat text, including party chat, and can detect less obvious bullying and harmful behavior beyond simple keyword matching. Riot stated it expected more than 20 times the volume of penalties compared to prior processes as a result of this system. The system assesses player behavior reports automatically and applies penalties without waiting for human review of each individual case.
