Yaaaaaaaawn....
Anyone who plays WoW has heard this from Blizz before - every now and then they go all ranty and sometimes even ban a few goldsellers etc...
Ultimately, the bans (if they happen) are of little matter - Blizz want players subscription money, and this usually outweighs any moral dilemma of removing goldfarmers, cheats etc - until enough paying subscribers make enough fuss to get another of these token responses.
I believe it when (if) it happens...
