If I got it straight, users can ask certain websites to vouch for their “personhood” and get a token that proves it. What exactly prevents a human from creating a token and hand it to a bot or crawler? How is it helping websites operators to differenciate legitimate traffic from the rest?
A human can, but as soon as that is discovered that human is rejected. They have to slowly develop a whole new persona, likely taking years - before they are trusted again.
At least for now when Kids regularly grow up enough to join the internet and so we have to have ways to let new people in. If tokens ever trade to a real verified human it may not be possible to get another. (though I doubt this - governments in some places will issue tokens to bots and real humans and so there is no way to tell without cutting off someone real.)
