I'll Take Bets
I'll take bets as to how long it takes for this person to get banned. Supposedly, Riot looks at post-game chat, but here's to arguing against it. Too bad Riot only cares about feelings in-game and not post-game....
Also, I posted on another account what someone said in post-game chat and got an immediate 7-day ban on the forums. Yet the player went on to continue playing after using the n-word repeatedly in post-game chat. Lovely system, Riot. Works as intended, right? Absolutely pathetic.
