Well, I got banned today, good-bye 4 mages, and mains. (Non Dual-Boxing Ban)

[Vyndree]

My girlfriends account, lvl 65 Hunter, banned.

Yeah, it was my fault though. I underestimated the importance of using real personal information when signing up to play a widely played MMORPG.

Warrior - Mickey Mouse
Mage - William Campbell (lets pretend thats my real name. I really did use my real name for Blizzard.)
Mage - William Campbell
Mage - William Campbell
Mage - William Campbell
Hunter - Minnie Mouse

I wouldn't be surprised if you were banned for the above, however, it's fishy that the GM told you you were being banned for using 3rd party programs to get past the global cooldown.

By any chance, were you using hardware like the g15 keyboard or the nostromo n52? Both of those can be used to get past the global cooldown.

In any case, be sure to follow up with account admin if the reason is indeed for using 3rd party programs (I hope you used a real e-mail address for those accounts).
If the reason is for account sharing, there's not much you can do. You might be able to get the accounts where your real name is listed back, but it would be a icky process. This would be the reason why we're adamant here on the forums that you be the original owner, and be LISTED as the original owner, on all of your accounts.
