I appears I've been banned while the servers were down, possibly due to typing in the password too many times to try to log in. I was doing AB at the time the server went down, in case that's relevant. Also tried logging on to the website to see why I was banned, but no luck there either (it's been up and down since I first tried).
At this point I can't see what I might've done to be banned, and am a bit puzzled, while I have seen several people in recent posts suffer the same problem just now so I suspect it is just a flaw somewhere.

Sincerely, Mims.
