Every frontier LLM in 2026 was trained on trillions of tokens scraped from the open web — and in 2026, most of those sites now actively block AI crawlers.
We put together a full guide on how AI teams collect training data at petabyte scale without getting blocked, poisoning their models, or getting sued:
🔹 Which proxy tier actually works against Cloudflare's "Block AI Bots"
🔹 What Common Crawl gives you for free (and where you must crawl fresh)
🔹 The WARC + distributed frontier architecture the big labs use
🔹 EU AI Act provenance logging — done at the fetch layer
🔹 How to strip prompt-injection and canary poisoning from raw HTML
🔹 A vendor checklist for ethical, audit-ready proxy sourcing
Built for AI/ML engineers, data pipeline teams, and anyone running crawls larger than "a few thousand URLs."
