Architecture of an Anti-Bot Protection

Describes how modern anti-bot systems detect scrapers using IP/proxy checks, TCP/TLS/HTTP2 fingerprinting (client_hello/JA3-style), browser-side JavaScript and canvas/GPU fingerprints, behavior tracking and ML classification. Shows a proxy aggregator called Scrapoxy that can spin thousands of AWS proxies and reports sustained usage, and advises layered evasion using headless or real browsers (Puppeteer/Selenium/Playwright), mixed proxies, and monitoring 100–200 signals (TLS, headers, WebRTC leaks, canvas) to reduce false positives.
