Also, I think these are just the terms for using the API. I'm not sure if they can do anything if I don't use the API.
Even If Yelp and Foursquare are a no-go, that still leaves 6 other solid review platforms to use.
Yelp and foursquare are useful but not the best. The granularity of rating for Yelp is too big. Over 50% of restaurants are 4.0 stars. (That's why the app is useful) Foursquare is the least used platform with the oldest reviews.
