This is Conjeng's TrustRating, which is based on both the number of reviews Conjeng 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 Conjeng has been to the Kudzu community.
Awesome Background Service, I will not hire without checking with Turnstone Background Services.
You have saved this business headaches and money. Keeping my clients and staff safe means a lot in my business.
