Ignored/Muted player Suggestion
If you get put on either one of the lists enough times should result in a Ban..
If I put a player on ignore, or mute I don't want him on my team next game. Next game the ignored/muted player should be on team enemy team. If I play solo/duo queues, or in any game. If he gets put on the either list 3 times in one day. well..... Ban. Take the random annoying players to the tribunal.
You will control player behavior this way.
