Along with their other problems ,small business has to deal with the scum from YELP...Watch the documentary,BILLION DOLLAR BULLY....Yelp has been destroying small businesses for over 10 years now....
I found this online:

I have no knowledge of Yelp personally. Those persons who wish to deal with it should ask nearby businesspeople their views and experiences.
I chose restaurants by volume of business and asking people leaving the establishment.
Gonna have to watch that.
