I really don't think someone should be banned unless they do something that is way too far past the line. The one big rule we have here is putting NSFW tags on NSFW threads, because that'll get someone fired. Someone who continuously pulls that sort of shit should go.
I also had someone sign up under the username 'farmer is a fag' and sent me a bunch of pm's, posted in a buy and sell thread of mine and on my profile page with a bunch of BS. Probably some jong who got butthurt because I told them to go fuck themselves, but what can you do. Pretty sure they got banned because it all disappeared suddenly after a day to two of it. I'm fine with that type of banning too.
But this is TGR. Pretty much everyone here should know what to expect. The 'meet the minions' thread pretty much sums up how awesome this place is, and if you want to reap the rewards of it, you're probably going to have to put up with being called a flaming faggot who skis in jeans. Shit, that's half the fun in this place.
