Yelp names and shames businesses paying for 5-star reviews

Yelp has started publicly naming and shaming businesses that pay for reviews. The review site's new index documents businesses offering everything from a crisp $100 bill for leaving the best review to a $400 Home Depot gift card for a five-star review. It also lists every business whose reviews have ever been suspected of suspicious activity, like spamming the site with multiple reviews from a single IP address.
