Fail Suspicious Reviewers

Take-Back Reviewers


1,351 of the 11,631 reviewers have had at least one of their past reviews for another product deleted. The Take-Back Reviewers have rated this product an average of 4.2 while the reviewers who don't have any deleted reviews in their history have rated this product an average of 4.0. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.

Warn Deleted Reviews

We discovered a total of 439 deleted reviews for this product, with an average rating of 4.3. Even though deleted reviews don't affect the average rating, the fact that action was taken to delete reviews raises some red flags about the integrity of the reviews for the product as whole.

There are a few limitations to keep in mind regarding the Deleted Reviews test:
  1. We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
  2. We have no information on reviews that were never published in the first place.
  3. We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.

We counted 11,631 reviews for this product over the span of 1,576 days, an average of 7.4 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 18 or fewer reviews on any given day.

However, we see the following 81 days exceeding this threshold:In total, we found that 2,430 reviews were created on just 81 days. This is an excessively high number of reviews submitted on these high volume days.
