I think we all remember when Amazon deleted the negative reviews for Hillary's book, WHAT HAPPENED---1-star reviews went first so some reviewers gave the book 5 stars then wrote negative reviews, just to get them up on the page:
Amazon was on the defensive end this week after receiving criticism for deleting negative reviews of Hillary Clinton's new book.
The online retail giant acknowledged its decision to remove one-star reviews of Clinton's memoir, What Happened, claiming they have the right to uphold reviews from legitimate customers.
“In the case of a memoir, the subject of the book is the author and their views,” an Amazon spokesperson told Fortune. “It’s not our role to decide what a customer would view as helpful or unhelpful in making their decision. We do however have mechanisms in place to ensure that the voices of many do not drown out the voices of a few and we remove customer reviews that violate our community guidelines.”
