Analysis Details
Take-Back Reviewers
61 of the 68 reviewers have had at least one of their past reviews for another product deleted. This is an excessively large percentage of Take-Back Reviewers which may indicate unnatural reviews.

- Created over 3 days
We counted 68 reviews for this product over the span of 56 days, an average of 1.2 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 6 or fewer reviews on any given day.
However, we see the following 3 days exceeding this threshold:In total, we found that 22 reviews were created on just 3 days. This is an excessively high number of reviews submitted on these high volume days.
37 of the 68 total reviews for this product admitted to receiving a free or discounted product in exchange for a review. This is an excessively large percentage of incentivized reviews which may indicate unnatural reviews.

Brand Repeaters
17 of the 68 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.

- Reviews have been deleted
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.
