Amazon has this problem with their &quot;Top 500 Reviewer&quot; category as well. I recently stumbled upon one of these whose reviews were all 5 stars, and all began with the same sentence. A quick look through that list also shows a few Top 500 Reviewers with zero reviews.<p>&quot;Amazon Bestseller&quot; and &quot;Top 500 Reviewer&quot; are concepts that form a large part of Amazon&#x27;s brand and value proposition. Regardless of whether this is a bug that can be quickly patched, they should pay more attention to things like this IMHO.
