This is yet another example of Cloudflare centralizing the web. I’m tired of this. Sure the only previously viable solution was ReCAPTCHA from Google. But it’s Google. I depend on them for search. And, sure, their business model depends on them being able to track me online. But I know them. And it’s hard for me to live without them. So I’m ok with depending on them, but I worry about further centralization of the In…

Well played sir

As much as I _despise_ modern ReCAPTCHA, I have always been able to pass the challenge eventually; it has never flatly rejected me with no recourse. If I made a mistake or was insufficiently human for it, I got a new challenge and tried again. There are apocryphal stories of Google tar-pitting users with it, but I have never seen it in action. If this judges the browser more than the user, what do I do when the brows…

I've had to go a few rounds with the photo match. Where I usually get tarpitted is by Cloudflare. I'll pass the (automated) CAPTCHA, the page will reload (still as if I had passed), and … it'll be another CAPTCHA. I'm pretty sure these usually amount to a passive-aggressive demand for cookies/storage, but I just vote with my browser & go back/somewhere else.

> go back/somewhere else.

But, haha fool you, CF now gatekeeps some unholy percentage of the web, so the "somewhere else" list is going to get smaller and smaller with no recourse, as best I can tell. Maybe disposable Firefox containers for your specific situation, but only maybe

Cloudflare: "Cloudflare has a long track record of investing in user privacy, which we will continue with Turnstile." Also Cloudflare: Tracks and fingerprints everyone, and blocks anyone who hardens their browser ("First we run a series of small non-interactive JavaScript challenges gathering more signals about the visitor/browser environment. Those challenges include proof-of-work, proof-of-space, probing for web AP…

There are no perfect solutions. In the arms race to protect against abuse, I'll take the solution that's more accessible, particularly to people that are discriminated against by CAPTCHAs, such as deafblind people.

> to protect against abuse

I would actually be on-board with such things if this were against abuse but it's not -- it's preemptively assigning blame, since my copy of Firefox is not modified in any way except uBO but CF loves to captcha it. The other stories in every one of these captcha threads, and the majority of the CloudFlare announcements at all, demonstrate this isn't isolated to "oops, our bad" but a systemic problem

If I were DDoS-ing some site, I deserve every ban I get, but just browsing via the provided navigation links on the site shouldn't "pardon our interruption" or gatekeep

If Google or Facebook offered Cloudflare $100B they’d probably have to take it. Add a quick TOS change and we are s-o-l. Hello gigantic super revenue earning centralized ad network (!$!$!). In all seriousness, I don’t see Cloudflare centralizing the web. I see them decentralizing it by empowering smaller folks with easier tools for scale. It’s a stretch of argument / not perfect —- but I am glad the competition exist…

Cloudflare's core asset is the trust. Sure, it's possible to capitalize on that, but then the game is over. I think everyone is aware of that.

Interesting. I wonder what other factors you might have going against you causing CF to captcha you - I have my Firefox loaded up with almost every ad-blocking, privacy, and anti-fingerprinting extension I could think of, but I rarely get CAPTCHAs.

> If this judges the browser more than the user, what do I do when the browser fails? Do I refresh the page hoping for a different batch of invisible challenges? Do I submit a ticket to CF customer support... despite not being a customer?

This is definitely good question. With the “Managed Challenge” feature it seems to degrade gracefully — if you have, say, a positive profile with Cloudflare, an iOS device where it can use PAT, etc. you never see the prompt but eventually it'll fall back to the same CAPTCHA you're seeing today. It'd be useful to confirm that this is how Turnstile works as well since some fraction of real people will definitely hit that on a daily basis.

It's still completely unusable on Tor. It hangs forever.

I almost fell for this one.

I read only a few lines then saw this comment and went back for the rest and changed my vote. So I did fall for this one. Thanks for the assist.

> only previously viable solution was ReCAPTCHA Erm, hello, hCAPTCHA[1] ?!? Can't remember when they started, but I certainly jumped ship to hCAPTCHA what is now many years ago now. Privacy protection is stated there on their homepage as their key differentiator with ReCAPTCHA. [1] https://www.hcaptcha.com/

you're replying to one of the earlier large adopters of hcaptcha. fact remains, its marketshare is still a lot smaller.
