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.)
