Blizzard has been lamenting for months now that most of their development time is spent combating Overwatch's negative community. While they'd rather be releasing new content, they have to focus on punishing bad players. They've been developing new systems to do so, and details for the most recent one have become clear today.
Players who engage in negative behavior, like cheating, negative/abusive language, and killing their teammates intentionally, will be marked. After enough reports of the above behaviors, a player will be marked “Needs Work.” If that player continues to rack up reports against them, they'll be bumped up to “Avoid Me.”
Players who have pushed the limit to the point of becoming “Avoid Me” status will suffer some consequences. The biggest of these will be the inability to use in-game voice chat on Xbox One. Avoid Me Xbox One players of Overwatch will be muted in all of their matches. This is the only platform that will mute Avoid Me players currently, but this option may move to the PlayStation 4 and PC in the future.
For now, if you're playing Overwatch on Xbox One and don't want to be muted in-game, play nice.
