Really? 14 days?
I just played a ranked game with two of the most toxic people i've ever played with, and i've been playing since mid-season 2 so that should tell you something. I just got a 14 day ban for saying that oh so terrible "R-word." Do you think the real toxic players in that game got banned? Probably not, because the instant feedback system literally just filters certain "terrible" words and auto-bans for them. The tribunal has been down for "maintenance" for like, 1.5-2 years now? So this terrible automated system is the only thing Riot has right now, and it doesn't catch the truly toxic players. Instead, it bans a player who has been loyal to this game for 4 years, just because he got frustrated with the toxicity and slipped up one word.
