What happened to me is this, I have 5 accounts and only 4 of them got the ban notice. it was all my clones my main account with my rading lvl 70 priest on it did not get the ban and I did not notice this until I wanted to move some stuff to one of my alt accounts after the raid, and by that time they sent out he e-mail that it was a mess up. the only fun part was trying to figure out what new password went to what account since they just said in the e-mail here is you new password. but once I figured that out I am back and running.

and yes Shit happens everybody makes mistakes they fixed it and it is all good
