Possible solution to toxicity, while maintaining player base.

Is it worth Riot's attempt to keep their company with as many people as possible for this fix.? The fix would be implementing a permanent mute feature to strictly players that flame/curse in-game. Could be tested by picking only a select few players who have received bans solely for toxic chat (not for griefing, giving up, cheating, etc). I'm not entirely sure if I would qualify, since I'm sure I've been reported for intentional feeding (even though losing to a snowball lane doesn't count), but nonetheless, other players should have a shot at playing the game while being verbally clipped. I love the game, I abhor the community. But please can permabans stop being handed out like candy from a robot that isn't the same as the Tribunal without some legitimate way of reforming? I feel like banning for toxicity is on par with considering marijuana a felony. It's not that bad. My god. Just shut their mouth forever, and they play.
