They remove valid complaints of businesses that screw people over if the squeaky crooked company wheel whines enough. Specifically I complained about Wings financial taking advantage of struggling families and not allowing them to refinance vulturous HELOC loans. They took my complaint down because I did not do anything other than say they were a bad business. I would have had to write a novel to explain what this poor example of business ethics did to cause me to write a bad review. Yelp caters to corps. All you need to know is they unfairly remove reviews when the businesses hire internet swipers to remove all bad.
