Done it on my realm all a buch of guys were banned...
Really Good Luck with this... flood the market and your name will be ban very fast...
Friends have done this a couple of mounts ago... all accounts lost.
Don't wanna flame this but really do you spect to fish at the WC Lakes without been seen?
And your name in the AH? Some ppl report situations like this just to investigate and guess what? BAN!
