There is nothing at all to worry about. Post your real name on a forum and SE will never do anything about it!
As for getting harassed by other morons, that might happen though. I mean shit if I hated someone in game I could just say what server and make an account on a hack site with that name and start talking about how I hack all the time lol. There is no "hard" evidence. SE is never going to ban because their ign is in a forum. Just wanted to get that off my chest for all the paranoid folks out there.
