The title is kinda misleading. This should mention Payload for vulnerabilities within the Ruby libs.

"We have noticed trends where fake review clubs/bots seed their reviewer profiles by leaving reviews on various products, specifically Amazon best selling products to create a profile that looks legitimate (it is done to fool anti-fraud systems that Amazon utilizes). Our engine detects these seed reviewer profiles and therefore penalizes them accordingly by examining their profile and our AI algorithm (one of numerous) was trained to distinguish these patterns."
I hope this is helpful. I love the website and I think it is not to the benefit of Amazon, Yelp, or TripAdvisor to do anything about fake reviews as it only helps their platforms generate more $.
