On Saturday, Wowhead posted a confirmation on their site, and then this Q&A with their CEO and the head of Affinity Media, John Maffei. They claim to be "100% sure" that since Affinity reportedly sold IGE, Wowhead will never carry gold ads. Farooq, the original tipster, posted an update on his site that says Affinity was "still very much involved with IGE," but Wowhead's Q&A says "the individual who leaked the story about the Wowhead sale" (apparently Farooq) also "owns competitive content properties," including a real-money trading (goldselling) site, and calls the act of that person spreading rumors about Wowhead "the height of hypocrisy." By all appearances, Affinity Media is no longer associated with IGE at all, and at the moment, the proof is in the pudding: there are currently no gold ads on Wowhead or Thottbot.
As for IGE, this report about the CEO at the Virtual Goods Summit makes it seem as though there are stormy waters ahead for their company and the entire gold selling market.
