Cloudflare Bot Manager is one of the most professional and implemented web security systems used to mitigate attacks from malicious bots. Unfortunately for us, web scrapers might be unfairly detected.
Cloudflare bot detection techniques include TLS fingerprinting, Event tracking and canvas fingerprinting. If you've tried to scrape a Cloudflare-protected site before, some of the errors you'll see include:
Error 1020: access denied.
Error 1010: the owner of this website has banned your access based on your browser's signature.
Error 1015: you are being rate-limited.
Error 1012: access denied.
These are usually accompanied by a Cloudflare 403 Forbidden HTTP response status code.
