@FreakyFwoof I get your point, I really do, but what alternative do you suggest?
Sure, ReCaptcha works with no email requirement, but that's only because they're Google and have it already. Audio captchas are a terrible idea, I've helped out non-english speakers over the phone with ReCaptcha enough times to know this first hand. Everything else (including audio) is trivial to solve in the age of LLMs and provides basically 0 protection. You can use weaker solutions and rely on IP reputation, but then blind people on "shadier" networks are completely out of luck, Google has this problem too.
HCaptcha is the worst system of all, except for all the others.
@miki Anything that isn't HCaptcha. A numeric problem, what is the number before four, plus two numbers after six? Add these together and type your answer. should be 11.
