It's a double-edged sword from what I hear, and completely based on which GM you get. I'd send in an appeal but don't admit to anything. If you feel you absolutely have to say you used PQR, perhaps playing dumb and saying you'll follow the WoW ToS like law and never cheat again might help you. There are plenty of posts around TBF regarding peoples' success and failure stories on appeals.
TBF = The Buddy Forum I can't think of any specific threads off-hand, but if you do a few searches throughout the forums you might come across a few examples people have sent in for an appeal. Like I said, 1% of it is what you say and 99% is whether or not the GM woke up on the wrong side of the bed. Plus, keep in mind that this is a MASSIVE ban/suspension wave. It's very likely that they won't even look at appeals from accounts that were shut down as a result of this. There's really no way to tell.
