I don't think that really has been documented elsewhere. There have been lawsuits and allegations, but no proof, as far as I know, that Yelp has offered to compromise their reviews for cash. Yes, they give business owners willing to advertise some editorial control over their listing, but the extent of that control is fairly well-understood and not much more nefarious than Google's text ads. Correct me if there's documented evidence otherwise.

Instead, we get article after article of business owners complaining because their Yelp reviews suck and their obvious attempts to game them have been thwarted. But that's exactly what Yelp should be doing. They're useless if they can be gamed. They're also useless if it becomes well-known that they're pay-to-play, but again, I don't think there's actual evidence of that. They'd have to be pretty stupid to take that course.
