Why have multiple account, just follow the rules and leave at that. If you break the rules, deal with it. There's no need to play games, I say, and do harsh things all the time, but I'm prepared to deal with what could possibly come behind that. This doesn't mean that I should use extreme profanity , get banned and rely on another account. That's not being real. it's childish, I will say what's on my mind , because I'm real, and except the outcome.
Having an alt doesn't necessarily have anything to do with ban-dodging, as has been pointed out.
