    Exactly. It’s called proof-of-work and was originally invented to reduce spam emails but was later used by Bitcoin to control its growth speed

      It’s funby that older captchas could be viewed as proof of work algorithms now because image recognition is so good. (From using captchas.)

        That’s actually a good idea. A very simple “click the frog” captcha might be solvable by an AI but it would work as a way to make it more expensive for crawlers without wasting compute resources (energy!) on the user or slowing down old devices to a crawl. So in some ways it could be a better alternative to Anubis.

        Interesting stance. I have bought many tens of thousand of captcha soves for legitimate reasons, and I have now completely lost faith in them
