Is it possible to scrape a website protected by Cloudflare?
A lot of websites nowadays add fingerprint checking. So even if you fake the headers - it wouldn't help, as cloudflare still knows you are making request from go / python / whatever. So there is a lib to spoof fingerptint - https://github.com/Danny-Dasilva/CycleTLS . It may work for you .

Stack under attack: what we learned about handling DDoS attacks
While it can still be spoofed using several packages , e.g. https://github.com/Danny-Dasilva/CycleTLS it can still provide a meaningful/easy-to-manipulate signal.
Moreover, most bots conducting L7 DDoS don't use real/headless browsers in order to be able to scale their attack, so it's highly likely they'll have a discriminating/inconsistent TLS fingerprint.
This can also be done directly in Fastly using e.g. https://developer.fastly.com/reference/vcl/variables/client-...
Another approach to proactively flag malicious IPs is to scrape free proxies. Indeed, most DDoS leverage lot of cheap/know bad IPs. It's frequent to see these free proxies in these attacks.

Show HN: Flyscrape – A standalone and scriptable web scraper in Go
Interesting. Can you compare it to colly? [0]
Last time I looked it was the most popular choice for scraping in Go and I have some projects using it.
Is it similar? Does it have more/less features or is it more suited for a different use case? (Which one?)
