Abstract: Toxicity-shield modules are activated with respect to participants of a multiuser virtual environment to shield individual participants from toxic behaviors. The toxicity-shield modules may be customized for each participant of the multiuser virtual environment based on tolerances of each participant for exposure to predetermined toxic behavior(s). The toxicity-shield modules may be activated during the multiuser virtual environment to monitor communications data (e.g., voice-based and/or text-based “chats” and/or a video stream) between the participants and to manage the exposure level of individual participants to the predetermined toxic behavior(s).
