Amazon's star rating system is broken and the fake reviews propping it up cost consumers $770 billion in bad purchases last year
Amazon removed 275 million fake reviews in 2025 and spent over $500 million on enforcement. Despite that, an estimated 30 percent of online reviews remain fake or inauthentic. The star rating that billions of shoppers use to make purchasing decisions is no longer a reliable signal of product quality.
Who has this problem

Small brands launching new products

Brand-protection teams at larger brands
Teams tracking review-selling networks as the FTC's per-violation penalties make enforcement real.
