Founder, Revdict

Andrew Keymaster built and runs Revdict, a free forensic checker for Google Maps reviews. Its scoring model has examined 420,533 public reviews across 443 places as of August 2026, flagging the patterns that show up in manipulated review records — same-day five-star bursts, throwaway reviewer accounts, and near-duplicate wording. He writes here about how those patterns are detected, what platforms will and won't act on, and what the data says about how common fake reviews actually are.
