Intentionally wrong reports

So, this jjust happened to me. I was playing riven and got WRECKED by a plat smurf leona/vayne top lane. I was not intentionally feeding, nor did i rage at my team members (i raged pretty hard at their teams in my team's chat). Was then reported for toxicity even though nobody was insulted, and got a FORTY FUCKING GAME CHAT BAN. People do this because riot essentially ignores reports for actually problematic things like trolling, but hands out chat bans a ton TBH i might quit league... i've had enough of this bs
