I had a soloq game in which teemo trolled and picked support teemo, then ran down mid while spamming. "fuck muslims, fuck you all" in all chat and racist stuff like that. Best thing is, I screenshot the chat with his score in the end and sent it to Riot support, and i got a response that they can't do anything and that I should try to respect summoner code. This guy kept playing(I kinda stalked him on opgg). Riot lost a faithful a player who was active for 6 years and spent some money on the game. What a joke.
