Alternative to toxic chat

So, this is just an idea, but there's a lot of people who are toxic in chat, but are legitimate players trying to win. They just get frustrated, and type the wrong things, and wind up getting bans. My proposal is instead of eventually perma-banning those players, why don't you just take all chat privileges from them? Everyone knows you don't NEED chat to play or win in League of Legends. It's not necessary, and you can communicate entirely with pings. Just take away the chat. Make it so that every player is on mute as soon as they come into the game, that way they can't see what's being typed at them either (to prevent harassment situations where they can't defend themselves at all). In my opinion, this is a win win. Riot still has players that are playing their games, they can't ruin games by typing toxic garbage all game, and they'll still spend money on the game. Perma-ban chat seems like a great solution to me. Reserve perma-bans for those players who just intentional feed, run it down, or somehow ruin games on purpose. People who play the game and try shouldn't be permanently banned simply for chat. Just my opinion though, let me know how you feel.
