I've only played with him the one time, and I'd gladly go back through the demo of it to find more reasons to ban him. It wasn't a pleasant experience.
There was mic spamming, bitching about the server, the reg, anyone with a ping over 60, he constantly was harassing Sniper because he stated that Sniper was jumping/skipping everywhere/shooting from behind walls/etc.
I tried appeasing him whenever I could, I spectated Sniper for several rounds, I saw no lag, and no jumping/skipping/rubber banding. I told Rapeface or whatever his name is that the dude wasn't lagging, and he started telling me off.
I told him to literally "shut the fuck up, I'm tired of hearing you bitch." He kept going so I banned him for that week*.
*(I had checked out his ban history, as I usually do when I'm contemplating banning for this kind of crap before giving him the week.)
I wanted to make it a lot longer than a week. I gave him several chances to just leave if it was such a big deal.
You can also see from his ban history that other players dislike playing with him enough to group together to ban him. You can't even get people to voteban an aimbotter.

If my vote counts, put me down as a yes.
