How didnt he get chat restricted or banned

I had a game with this toxic guy he wasn't toxic in game but in lobby he was. He was mad at his teammate and i trolled around and was just saying dumb stuff like "OH WHAT A ROAST, OH MY GOD HES IN DENIAL NOW WHAT A ROAST, DESTROYED WOW" siding with 1 person the guy i didn't side with told me to kill my self like 5 times, told me I'm a useless piece of shit like 5 times asked me when i live "so i can slit your useless throat" and was incredibly toxic.

He didn't get punished whatsoever, or it hasn't sent me the message that he was punished, i've seen people get chat banned for saying just for saying "kys" this guy did much worse how doesn't he deserve to get chat banned or restricted. I'd post the guys username but i don't think that's allowed. Sorry for English it isn't my primary language.
