Amazon uses machine learning to automatically detect and remove fake, manipulated, or AI-generated reviews across its platform, including user reviews posted about Prime Video titles. The system uses pattern recognition on review text and behavioral signals to identify suspicious submissions.

Amazon's automated review moderation analyzes text for patterns associated with inauthentic activity, such as repetitive phrasing and unnatural writing style. Behavioral signals — such as the account age, geographic location, and review timing — are also factored in. Amazon has publicly stated it employs more than 12,000 people working on fraud and abuse prevention. In 2022, the company reported discovering 10,000 Facebook groups organized to solicit fake product reviews. Amazon's policy permits AI-assisted reviews as long as they represent the reviewer's genuine experience. There is no separate Prime Video-specific review moderation system; Prime Video shares Amazon's platform-wide infrastructure.
