Ain't it cool? Protection rackets are learning how to do PR and posing themselves as nice guys doing the right thing.

Edit: Yelp business model is basically taking the "influencers" game to scale. Remember when we were promised the "knowledge of the crowds"? Yelp, Putin and Facebook were smarter and gave us digitally manipulated lynch mobs instead. It seems far easier and more profitable to harness and manipulate ignorance than knowledge.
