The combinations of formats and editions make it impossible for readers to pick between multiple versions of the same products, and allow those selling badly put together editions to piggyback on good reviews.
At this point, Amazon should just admit that its review policies are a complete shambolic mess. If they refuse to allow fellow indie authors from reviewing each other and even prevents their own friends and relatives from reviewing their work, how can Amazon justify trying to sell dreck this way?
Hypocrisy.
