Nostalrius Begins - Quality wow vanilla realm (1.12)

Greetings. The servers have been acting weird all day while I was doing BGs and when I recently tried to log in I got a prompt saying I was banned. After logging on to the main site and checking my email there still is no given reason for it. I even went through the list of reasons for getting banned and I didn't fulfill any of them.

I play on the characters Strafir and Strafirz on the PVP server. What exactly is going on?
