I just had the most toxic enemy team ever

These 4 guys in the enemy team, from the beginning of the game, started to verbal abuse my team and use hate speech.
They said stuff like "Kill all the Nixxers" "and Chxxks too" "Get fucked" "Shut your shitty little mouth and eat my dick" and many other shit that I don't want to post on the board
I wish some sort of punsihment can be put on these guys, they literally used more inappropriate words in this one game in all chat than what I have seen in my entire history of playing league of legends.
