In my experience Amazon is designed to block reviews that call out questionable products, Amazon is designed to make returns difficult for fraudulent products. "You pay for the shipping", hide all customer service options related to seller issues, etc etc. Amazon is complicit in the fraud committed by their sellers. They restrict critical reviews by people who bought fraudulent products under the guise of a tos violation. They should be retroactively contacting customers who purchased products they have removed for fraud reasons.
