Hello, sorry that I did not update you sooner on this issue. I have just checked the logs, and it seems that a bot named "DragoonFlame" has hacked your account. If I was you, I would recommend that you change your password and your security questions, and also change your e-mails password, as he has access somehow to your account. You must have given him your password or logged into a keylogger that he made.
Anyways, I have gone ahead and IP Banned DragoonFlame, and deleted his characters out of our database.
Have a wonderful day.
