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.

Recent 'MFA Bombing' Attacks Targeting Apple Users
> us[e] Akamai to block scraping
Would https://github.com/lwthiker/curl-impersonate help? Haven’t tried with Akamai, but did help with another widely used CDN that shall remain unnamed (but has successfully infused me with burning hate for their products after a couple of years’ worth of using an always-on VPN to bypass Internet censorship and/or a slightly unusual browser).

Get RSS feed for your Ko-Fi account
But before that, I had to create a development environment where I could do the coding. I used Docker and created a docker-compose.yml file on my local system to build a container. At first, I did that on an Arm based computer and the first problem appeared. Although RSS-Bridge was working fine, I couldn't get any data, and the reason was that Ko-Fi.com uses Cloudflare CDN. This is something that a lot of people had issues with in the past. RSS-Bridge solves that problem by using a special build of curl that can impersonate the four major browsers: Chrome, Edge, Safari & Firefox. But unfortunately, that library doesn't work well on Arm-based systems, so I had to move to my trusty Intel-based Linux computer.

- Weird API behavior: Only Postman and browser consistently work but making same request with requests library gets a Captcha instead.

I haven’t seen a custom build of Wget, but for Curl there is curl-impersonate[1].
