This is Jaspercat's TrustRating, which is based on both the number of reviews Jaspercat has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful Jaspercat has been to the Kudzu community.
