Wowhead and Thottbot on ad strike

Thottbot and Wowhead, two of the most popular WoW database sites, have been having a few problems with ads lately. There was that brief issue with the trojan in a banner last month, and also apparently some rather irritating ads with flashing and sound have been showing up lately (and I think we can all agree that ads with sound are evil). But, like much of the Internet, these sites are kept free for us because they are ad-supported wow gold, so what can they do? Well, they've gone on advertising strike.
