Amazon doesn't require purchase to post a review; they want people to post reviews of books they already own.
This mostly falls under "all complex ecosystems have parasites"--it doesn't matter how effective your scarecrows & pesticides are; if you don't assign a human to protect the crops at some point, bugs & birds will destroy the field. Amazon & many other sites want an all-automated protection system, and it's never going to be entirely effective, and never going to be effective enough after activity gets past a certain level.
