Walks through concrete defenses and tradeoffs: starts with user‑agent and robots.txt and public IP reputation lists, escalates through rate limits then 30 million IP addresses residential botnets, shows the concrete cost to attackers like $137 a month, adds browser checks, proof of work cookies, fingerprinting, payload analysis, ML scoring and coordinated detection, captchas and randomized responses that return slightly wrong prices to poison scrapers — explains what was built, costed and when each layer actually works.
