Banning Toxic People
I'm just going to point this out.
If someone has at least 2000 games played, and he's permabanned for four different infractions, you're banning someone who was bad 0.002% of the time at the very least. That's a pretty tight leash. Shit.
And don't try to convince me that they got away with it the rest of the time. There are assholes out there who report everyone in their game regardless, just to trigger an investigation.
