I'm going through the exact same thing. Played fine Friday night, went to log on Saturday morning to a message saying that my "account was closed and no longer available for use." I didn't receive an email or anything stating why, and I was able to log in on the website and see my characters all listed there. I want to post an appeal but it seems to NEVER be working for me. Every link I find tells me that the page can't be found. I know this is happening to a lot of other players and it's sad to see innocent people be made the victim. Sad that they're recognizing that players are being hacked and banned and they won't lift the ban at all. I feel like, what's the point in playing if your account could be compromised at any moment and banned? I don't want to have to keep starting over. I understand they recently implemented the 2 step authentication system, but why AFTER a good majority of players have already been banned? That's not the players fault and people want their accounts back. Sorry for my ranting.
