How do you spot a bot-written negative review before you respond to it?

For business owners — what tells have you actually seen when a negative review looks bot-written rather than like a real unhappy customer? A burst of 1-stars close together, reviewers with no history and one review total, no specifics (or details that don't match what the business sells), near-identical wording across different names, and no record of that person in your own books — no appointment, invoice, or receipt. Real unhappy customers are usually too specific. Bots are vague, polished, and everywhere at once. I don't accuse anyone publicly — a real customer misread as a bot is worse than a bot left up. Flag it, keep your own record, reply calmly once. Full disclosure: I'm the founder of proofix.ai, which only lets a review be created when tied to a verified receipt.
