I'm getting real tired of being punished for quitting games. I'm getting stuck in games where people leave after the map is voted on or just go afk the entire game. It's not fun to play those games when I'm at a disadvantage from the start and those people continue along, yet I'm punished for wanting to find a new game.
You can easily avoid getting banned if you play your matches. You can fix this issue by playing the entirety of your game all the way until the end. Hope this solves your issue.
