I don't know...when I transferred my Monk to another account (just days before I was caught using GK) the GM said there was no information on my Monk and that he would have to delete the character because he had no way to roll him back (luckily I only lost a level, 100AAs, and all of my gear). The Monk didn't have any GM issues before. But what teh GM said that leads me to believe that the marks are tied to the account and not the character. That's just a guess, but I have always heard that the marks were against the account not the character itself. So in theory, you should be able to move the toon(s) to a new account and be safe. Just remember, any Veteran AAs you have will be gone if the account is new.
