We get it. Ads are annoying and nobody clicks on them anyway However, servers and staff are expensive! We are not going to ask you for money or banner clicks. Instead, we ask that you please share our site. Letting other people know about our tool is much more valuable to us than a few ad impressions.
We discovered a total of 2 deleted Reviews for this product, with an average rating of 5. 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:
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.
We counted 1,657 reviews for this product over the span of 8,107 days, an average of 0.2 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 3 or fewer reviews on any given day.
However, we see the following 159 days exceeding this threshold:
The ease score is the average rating for all reviews that a given reviewer submits. The average ease score for reviewers of this product is 4.5, while the average ease score for reviewers in this category is 4.4. While this discrepancy is rather large, it is not quite large enough to rule out the possibility of it being due random chance.
In total, we found that 1110 reviewers (or 68%) are within an overrepresented participation group. This is an excessively high number of reviewers in overrepresented participation groups.
