Hello.

Cloudflare's Browser Intergrity Check/Verification/Challenge feature used by many websites, is denying access to users of non-mainstream browsers like Pale Moon.

Users reports began on January 31:

https://forum.palemoon.org/viewtopic.php?f=3&t=32045

This situation occurs at least once a year, and there is no easy way to contact Cloudflare. Their "Submit feedback" tool yields no results. A Cloudflare Community topic was flagged as "spam" by members of that community and was promptly locked with no real solution, and no official response from Cloudflare:

https://community.cloudflare.com/t/access-denied-to-pale-moo...

Partial list of other browsers that are being denied access:

Falkon, SeaMonkey, IceCat, Basilisk.

Hacker News 2022 post about the same issue, which brought attention and had Cloudflare quickly patching the issue:

A Cloudflare product manager declared back then: "...we do not want to be in the business of saying one browser is more legitimate than another."

As of now, there is no official response from Cloudflare. Internet access is still denied by their tool.

I'm using chrome on linux and noticed that this year cloudflare is very agressive in showing the "Verify you are a human" box. Now a lot of sites that use cloudflare show it and once you solve the challenge it shows it again after 30 minutes!

What are you protecting cloudflare?

Also they show those captchas when going to robots.txt... unbelievable.

I run a honeypot and I can say with reasonable confidence many (most?) bots and scrapers use a Chrome on Linux user-agent. It's a fairly good indication of malicious traffic. In fact I would say it probably outweighs legitimate traffic with that user agent.

It's also a pretty safe assumption that Cloudflare is not run by morons, and they have access to more data than we do, by virtue of being the strip club bouncer for half the Internet.

Many / most bots use Chrome on Linux user agent, so you think it's OK to block Chrome on Linux user agents. That's very broken thinking.

So it's OK for them to do shitty things without explaining themselves because they "have access to more data than we do"? Big companies can be mysterious and non-transparent because they're big?

What a take!

Can't the user agent be spoofed anyway?

I think they also fingerprint the browser. So changing user agent alone won't help.
