Amazon has scrubbed hundreds of one-star reviews for Hillary Clinton’s "What Happened" following the book’s recent publication, according to Quartz.
Quartz reported Wednesday that 1,669 reviews of the memoir existed late that morning, with about 50 percent with one-star ratings and 45 percent with five-star rankings.
The total included only 338 reviews from users with verified purchases of the book, which denotes customers who actually purchased the item on Amazon.
The Guardian on Thursday reported that 581 customer reviews remained that morning, with 95 percent assigning five out of five star scores.
“We remove customer reviews that violate our user guidelines,” Amazon said in a statement Thursday.
“When we find unusually high numbers of reviews for a product posted in a short period of time, we may restrict the number of non-Amazon Verified Purchase reviews on that product,” the online retailed added of its guidelines.
“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.”
Some Twitter users on Thursday criticized Amazon for managing the customer reviews about Clinton’s book.
Quartz reported that it noticed a discrepancy in reviews of Clinton’s memoir on ReviewMeta, a site that aids customers in determining the credibility of Amazon’s product reviews.
ReviewMeta found that the average rating for reviews of the work from unverified buyers was a 2.3.
The average from a verified buyer of "What Happened," according to ReviewMeta, was about 4.9 out of 5 stars.
ReviewMeta additionally discovered that Amazon’s overall rating of the book would have been 4.9 stars when adjusted to its metrics rather than the 3.2 star score it had Wednesday morning.
Clinton was the 2016 Democratic presidential nominee, and "What Happened" is her controversial new memoir about last year’s White House race.
The book came out on Tuesday and has since reignited national debate over Clinton’s loss to President Trump last November.
