Data audit of LingoMastery.com: Forensic evidence of synthetic 5-star review inflation A "Ghost Rating" is a star-only rating left without a written review. To understand the scale of what I’ve found, imagine these ratings as an empty storefront that looks packed with happy customers from the street. But when you walk inside, you realize the store is completely deserted—the "customers" were just cardboard cutouts placed there to trick you into coming in. **These ratings are intentionally difficult to audit, acting as a "blind spot" that allows bad actors to manipulate Amazon’s ranking algorithm without leaving any trail of evidence.** I’ve spent the last few months performing a forensic audit on a major publisher in Amazon’s language-learning category, **Lingo Mastery**. I’m a language professional, and I became concerned about the integrity of the materials being fed to students. I found patterns that suggest this is probably not a traditional publishing house, but most likely an automated SEO content mill. **Would appreciate a sanity check from others here.** **The "Ghost Rating" Flip** When these books launch, they look "human"—about 94% of initial reviews are written. But look at their established "Best Sellers" (published 2018–2020) let's take Japanese Short Stories for Beginners as an excellent example: ·       **Total ratings:** 1,866 ·       **Written reviews:** \~6% ·       **Rating-only (Ghost) reviews:** \~94% ·       **Velocity Collapse:** The books have suffered a 500+ day drought of *written* reviews, yet the 5-star count continues to climb steadily (no written 5-star reviews since 2024), however still rank highly in search. I focused on their flagship Japanese title as a clean example, but I am seeing the same 'Velocity Collapse' and 'Ghost Rating' patterns across their entire Russian, German, and French catalog. The data suggests this isn't an anomaly; it is the standard operational procedure for their entire portfolio. **What stands out**
