Cheapest WOW gold on fan sites are one thing (we've been plagued by them in the past, ourselves), but today Cheapest WOW gold  are starting to turn up on the official Blizzard forums!

The above screenshot was taken by me at about 3:15 EST this afternoon. This is a major (and hilarious) slip-up on the part of whoever handles the advertising on the forums (which was just put in fairly recently). I expect to see a lot of people Cheapest WOW gold  and trying to claim that Blizzard endorsed it with these ads, and then getting confused when their accounts get banned.
At the moment Blizzard forum moderators are apparently deleting all threads pertaining to the ads, which seems appropriate enough; they clearly know about the problem. Oh, and folks: don't buy gold.Blizzard has responded officially to the matter, stating: "Recently, there was a temporary error with our forum advertisements that caused a gold-selling ad to be displayed. At this time, we have resolved this error. Our stance... remains firmly against the buying or selling of gold, and we may take action against accounts that are involved in these activities."
