What Hacker News says?

  1. There are some attemps to make proof-of-human https://herrjemand.medium.com/why-cloudflares-captcha-replac... https://www.proofofhumanity.id/ But in the end it comes to the fact that your Google/Apple needs to have your app store account that is verified to be human enough (less fake accounts) and then a web browser confirms this via a login to this account.
