I did. In WoW. I had stopped playing for about 4 months then I got an e-mail saying I had been banned. Turns out someone hacked my account a month after my subscription ran out and used it to gold farm. I had to go through about 5 different departments for things like getting unbanned and having my stuff restored. They continually said the account was a fixed but I still had the ban on, even though they said it was lifted. Eventually I just gave up and stopped trying, turning the other games instead.
