Cloudflare crawl respects robots.txt. It does not attempt to bypass any anti-crawling measures. If the site doesn't want to be crawled -- whether it uses Cloudflare or not -- this product will not help you crawl it.

Some sites actually want crawlers -- e.g. sites that are selling a product, documentation, etc. That's what this product is meant for.
