Now, I know you can just leave when the match is over. That's obvious, the problem with these two guys is that they're so toxic I just know they're most likely always like this. So even if I can just ignore them, that doesn't mean they're going to stop acting like this. How do I report end game chat if I have screenshots of their extreme racism, homophobia and the like?
Use the standard report system and mention that it was for post chat-behavior. Although the post-chat is not automatically scanned with the detection system, it's still something that is recorded. A manual review would still be able to spot it especially if this particular player has received a lot of reports mentioning their post-chat behavior in the details.
by the way you should change your summoner name before riot take action again your account.
