Amazon has structured their reviews to enable unethical behavior by sellers. Any review which comments on the seller or seller's behavior is removed because the product page is supposed to be a page of seller-agnostic reviews of the product. There is a separate page of reviews for each seller, but it is buried to the point that no-one looks at it. It makes it leaving reviews about sellers doing unethical things like paying for reviews fruitless: either you put it on the product and it is removed quickly, or you put it on the seller and no one sees it.
