In Dota 2, I've noticed that whenever I report someone, I (happily) never see any messages from them for the rest of the game. As I highly doubt trolls of the nature I've encountered would just suddenly be completely silent, I suspect there's some other mechanic at work here.
I've also been threatened with a report by a rather abusive player I encountered recently, and yet I noticed that after he claimed to have reported me, he was still giving me helpful advice like "shut up retard". Does him responding to me prove he didn't report me?
Does reporting someone mute them? Is it possible to remove this mute?
