CF turnstile is one, but of course that means Cloudflare owns even more of the web.
HCaptcha is inaccessible and actively discriminatory against individuals with disabilities and refuses to change, to the point that I suspect the only way that they will do anything is to file a class-action against them and sue them into the ground.
And I... Can't think of anything else. Other than to just get rid of Captchas entirely.
Enough to make it so bots are expensive to run.
You could just call them.
But in all seriousness, many services are making it difficult through to impossible to communicate outside of their web or app platforms. Call centres are expensive and messy, and it's now apparently acceptable as a society to treat customers/clients/whatever as adversaries so they can get away with making it hard to communicate with them.
Are you comfortable with anybody being able to ring up the hospital and say "yo, it's majorchord, how are my gonnorhea results?"
No, that's why we have safety protocols in place. When you call a doctor they ask you for your birthdate or sometimes also a PIN/password on your account to protect your data.
How would that still be considered a breach of privacy?
But giving birthdate (available to anyone via a single query in a public database) and (sometimes?! - what?!) PIN over the phone wouldn't really be considered good enough here. Birthdate is, as I said, public knowledge. And a phone is too insecure a medium for transmitting a password.
I'm not super interested in an long argument about whether it's reasonable that this isn't considered secure or not. I'm just letting you know what reality looks like. And the reality is that "just call them" is not a solution, because such information will simply not be handed out over the phone.
It already is a solution, and has been in widespread use for many decades. I don't think it's going anywhere.
Suddenly I have been made aware that, having lost my paddle on Shit Creek, I will eventually be taken downstream to Shit Lake (where it appears I will inevitably drop anchor).
People do care about such things.
I hope the same is true in other EU countries.
No. Bigger problem created, since there are innumerable government, health care, and educational web sites that use reCAPTCHA.
I'm not going to give up reading the test results from my doctor because of some simplistic ideologue decides that it's "problem solved."
