Yelp has a wall of shame for businesses caught paying for fake reviews
(www.engadget.com)
This is a most excellent place for technology news and articles.
Because it's not about normal people browsing it, it's about them saying "we put you on our wall of shame "pay us instead of those fake reviewers!" And then removing the business from their tidy, alphabatized, excel spreadsheet that the esoteric algorithm the "wall of shame" randomly pulls from.
It's about blackmail :D
