Not sure if AsianHustleNetwork (AHN) really falls into what's being described in this article, but it's one of the more insidious FB communities I've run across, in terms of members being milked for affiliate revenue.

The content is overall wholesome and useful, but I'm assuming most members (both contributers and passive viewers/clickers) don't realize that they're lining the owners' pockets with their clickthroughs, along with whatever personal data is being collected through Facebook.
