So apparently a crackdown on account sharing by some of the best arena players happened and a few of them including cdew and filo were banned.
Anyone have any more details. I found something posted on blizz forum site.

Shame. Now the NAO is going to be ruined. But thats what happens when you break the rules i guess. It just seems so arbitrary to single out these guys when there is account sharing in the thousands everyday all over the world.
