I guess I'll actually post some original stuff while I'm here.

1. Someone else's game. Evilo surrendered turn 1, the other players voted except for Johnny. Then, Johnny boots and collects easy points.
2. Someone else's game. Evilo spams the chat
3-6. Evilo and Johnny spamming the chat. There could be much more than 3 screenshots of that.
I personally just blacklisted them because it is annoying to have in the game. The Africa game also had them drawing out the game about 20 minutes before we eliminated them. Their teammate decided being booted was better than being in the game. You might be fine with all this, though. Your decision in the end.
