1) Facebook might be able to distinguish real friends from social gaming faux friends, but advertisers aren't given that information today. They can target "friends of friends" of people who appear to have a particular target interest (for example), but that's going to have a lot of noise because of the social noise.
2) When people lie by spending real dollars, at least their spending real money. And they are actually saying something. Maybe it's not "I'm a race car driver", but "I'm interested in race cars". The trick is understanding what it is they are saying.
