    Any bot? That’s just impossible. We’re going to have to tie identity back to meatspace somehow eventually.

    An existing bot? I don’t think I can improve on existing captchas, really. I imagine an LLM will eventually tip their hand, too, like giving an “as an AI” answer or just knowing way too much stuff.

    How would you design a test that only a human can pass, but a bot cannot?

    Very simple.

    In every area of the world, there are one or more volunteers depending on population / 100 sq km. When someone wants to sign up, they knock on this person’s door and shakes their hand. The volunteer approves the sign-up as human. For disabled folks, a subset of volunteers will go to them to do this. In extremely remote area, various individual workarounds can be applied.

      This has some similarities to the invite-tree method that lobste.rs uses. You have to convince another, existing user that you’re human to join. If a bot invites lots of other bots it’s easy to tree-ban them all, if a human is repeatedly fallible you can remove their invite privileges, but you still get bots in when they trick humans (lobsters isn’t handshakes-at-doorstep level by any margin).

      I convinced another user to invite me over IRC. That’s probably the worst medium for convincing someone that you’re human, but hey, humanity through obscurity :)
