@dongrandy What type of information are you looking for?
Here’s my experience with Yelp filtering reviews.
Yelp will filter a review if the reviewers profile isn’t filled out.
Yelp will filter a review if all the reviews the reviewer writes are 5 stars.
Yelp will “hide” a bad review if the business owner has answered the initial review and offered to make the bad experience right and the reviewer answers the business owners reply with another nasty comment.
