Live-coding shows a working pipeline that uses Scrapoxy proxy waterfall + Scrapy and Playwright-driven browser farms to get 50 item pages past headers, IP rate limits and JS fingerprints, with dynamic spin-up/shutdown of cloud VMs to cut cost ~80%. Demo includes deobfuscating an encrypted anti-bot JS payload and replacing it with a forged submission so requests succeed without full browser rendering — practical tradeoffs and concrete commands, and a 1,900‑star GitHub project.
