Strange that it's only one account getting hit. You'd think if you were doing an exploit or something bad, they'd ban all of the accounts, not just one.

I'd write in to the GM feedback e-mail, and ask for clarification of why the account was banned. That e-mail goes to the GM supervisor.

Are you sure your account(s) are'nt compromised? Have you run all of the scans you can? Have you checked on other realms for level one characters?

And, the one I'm most curious about, are you running tunneling services? That seems to trigger a lot of bans, in the Customer Service Forum there was a wave of them recently.
