Silence
Why doesn’t WoW have its own player toxicity strike team?
Overwatch has gotten a bit of a reputation for toxicity.
Heroes of the Storm combats toxic players with silence penalty
While you can currently report players in Heroes of the Storm for harassment and general bad behavior, coming in the next patch you'll have a wide range of additional reporting options — and reported players will receive a new punishment with silences that greatly restrict their ability to chat.
