My experience today.
Today I was viciously harassed all game by someone who also threatened to report me, since I wasn't playing how he wanted me to. (I was split pushing instead of grouping) I said I had done nothing wrong, what is there to report? He said it doesn't matter, 4 reports in one game is 4 reports in one game.
Today I played another game, with a bottom lane that fed constantly. I said absolutely nothing bad to them during the game, and in the lobby after, I just agreed with someone who said our bottom lost.
Today I received a notification that my behavior is "not in line with the community".
Today I lost a lot of faith in Riot.
