Blizzard instituted an action in Federal courts seeking at least injunctive relief from Peons4hire, a gold farming service notorious for spamming gamers in-world with advertisements for cheap gold. Player response has been overwhelmingly positive.
Peons4hire are about to become unemployed4hire
I doubt that this gold farming operation has the resources to challenge Blizzard, but it will be interesting to see how this case comes out from a virtual property perspective. Will Blizzard attack them for their violations of terms of service regarding the acquisition and sale of its virtual property? or only for spamming in game? If they do not go after the farming itself, will that imply that they condone it? Or, do they just know that as long as there is demand, there will always be farmers...
Ironically, right next to this story is an ad for WoW Cheap Gold...WoW!
