Analysis Details
Fail Suspicious Reviewers
One-Hit Wonders
2 of the 8 reviewers have only reviewed this product. While this is more One-Hit Wonders than we'd expect to see, it does not appear to have a significant impact on the overall rating.
Take-Back Reviewers
3 of the 8 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 5.0 while the reviewers who don't have any deleted reviews in their history have rated this product an average of 2.2. 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 Brand Repeats
Brand Repeaters
2 of the 8 reviewers have reviewed other products for this brand. While this is more Brand Repeaters than we'd expect to see, the discrepancy in ratings between the Brand Repeaters and non-repeaters isn't significant enough to rule out the possibility of it being due to random chance.

There are a few limitations to keep in mind regarding the Deleted Reviews test:
There are a few limitations to keep in mind regarding the Deleted Reviews test:
- 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.
- We have no information on reviews that were never published in the first place.
- 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.
