You can't prevent spam like that. Rate limiting: based on what key? IP address? Botnets make it irrelevant.
Proof of work? Bots are infinitely patient and scale horizontally, your users do not. Doesn't work.
Micropayments: No such scheme exists.

- jve 1y agoMany countries at least in europe have digital identity systems. For example ID card which replaces passport and is a smartcard. You can sign documents and authenticate online services. All gov + many other services let you log in with this ID. I can also have an app on mobile for auth purposes which gives strong guarantees that the person A is actually the person A. Anyways, I wonder if there is a service that unions all those official auth methods for countries so there would be a global solution for website login. Certainly there would still be countries left in the dark, like USA :(
