This is the kind of thing that should be punished (A case for fair in-game moderation (names black))
That is a clear cut case of toxicity.... and yet this kind of player is found disturbingly often... while on the forums I often see chat logs that don't even have a fraction of what this person was like in game. Basically it seems as though the disciplinary team comes down extra hard on people that are low on toxicity but is very forgiving towards people with toxicity.
It should be the reverse, shouldn't it? And yes, that guy got reported by everyone... but I didn't get the punishment message so it did tuck all, for all the good it did. Might as well not have done anything.
