YELP Sued for Extortion of Small Businesses (by Posting Fake Negative Reviews)

A summary of all these public video is: positive yelp review is removed, negative yelp review appears, then yelp sales representative calls a business about paying for advertising.  If businesses don't pay, then worse things happen.  We are not ok with blackmail.  We will not advertise with yelp.  In fact, we do not advertise much, most of our patients comes from referral of existing patients.
