These ARE verified purchases. You can buy them and just have to pay the reviewer for the purchase (or set the ebook to free for a limited time and let the reviewers download/"buy" the ebook in this timeframe). However, the strategy is not sustainable: Most 5 star reviews get "not helpful" marks and the ranking honors the number of purchases as well. The ebooks in question already get newer 1 star ratings and will take a nosedive when no new fake reviews are coming in.
