Well...
I don't think manners make much of a difference over there if they have you pegged as a troublemaker. People like Ambulance Chaser, KingOfRhye and Michael C manage it somehow, but I can't always manage to keep the lid on the pressure cooker and so my mouth begins to work for the prosecution.
And since I have an IT background and can always get around their idiotic bans, even when they IP ban me, I can always come back...I have had dozens of accounts. It's always the same, they last a couple months, they get zapped, people like Guest Verified and Jason Todd smugly high-five each other, and before either of them realizes it, they're getting bombed by me all over again.
Which is why it's really so dumb for anyone to mention "sock accounts" over there. If people like the Christian News Network censors and Lady Checkmate would stop their ridiculous bans, people wouldn't create new accounts and come right back. It's all a silly game.
Also, since I know how to create Disqus accounts lightning fast now, I can treat them as disposable whenever I like and occasionally say things that I KNOW will get me banned, but who cares? Sometimes it feels good just to tell someone off...
