If I kill cheaters on my own team in CS:GO, will the match still count as a loss after they get VAC banned?
Solution 1:
If a player is VAC banned all wins that player had are invalidated, therefore, you and everyone else on your team recover your lost mmr after he's banned. ( I've seen this happen before where someone on my team was cheating and I recovered my elo )
Also, don't kill them, since you could get reported and get overwatch banned for team killing.
The best thing you can do is report him every round.
