Yep. This is the reason I don't say anything in game most of the time. Unless I get one of those bizarre games where everyone is chatty and nice, I just don't bother. It's not worth it. I don't need to deal with getting reported because somebody didn't like my performance and so they reported me because I might have been a bit negative as a result. I feel threatened as a player, constantly concerned I might say something that upsets someone and it triggers the wrong flag, getting me banned or muted. And I think it's ridiculous, I shouldn't have to be some ray of sunshine to chat. I should be able to say a game is over, defend myself from harassers, discuss the possibility of why we're losing, etc., without getting muted. I hate how Riot is trying to turn this game into some form of safe space. Let me vent, my team can mute me, let me defend myself, I'm being harassed and it hurts, let me speak my opinion as long as I'm not being some racist bigot. Why must I appeal to every person I meet, out of fear that they will get upset and report me? No other game does this. As long as I'm not being some racist piece of shit, I don't have to worry about getting in trouble. Now I have to censor myself on the off chance I upset someone or Riot doesn't like my word choice. Even saying "shit", on Riot's boards makes me nervous, where nowhere else would I be afraid of cursing.
This company seeks to censor and silence and it's frustrating.
