Err; warden is capable of picking up certain third party programs as far as I'm aware. A couple of weeks ago, I was banned for no reason either, 3 day ban. Aparantly I'd been using a hack of sorts but I -knew- that was impossible. Aparantly, someone'd hacked my account and tried to log in with a hack and got my account instabanned before he even got past the char screen. After a ticket the ban was removed from my account. So check up with that. See if someone else may have logged into your account.
