I know a lot of people who post reviews on Yelp, both positive, in-between and negative depending on their experience. Matter of fact, Yelp has a system in place that will not post the reviews of people who only leave negative or positive reviews.
They also have a system in place that “recommends” certain reviews over others. Only those count towards the overall rating. Which basically filters reviews to their liking. Yelp is a joke.
Yelp, shmelp. Your discourse on PCGS is downright libelous...........better hope they don't see your raucous postings.
