But how can this be done so that the site and I'd verifier can't collude on a backchannel to unmask you?

I don't advocate for destroying private property. Sharing tokens doesn't destroy property or ip/copyright.

Now we're talking :-). Look at Privacy Pass, it's interesting!

If you like RFCs, it's here: https://www.rfc-editor.org/rfc/rfc9576.html

Kagi has a nice explanation here: https://help.kagi.com/kagi/privacy/how-does-privacy-pass-wor...

Thanks. I appreciate the link. One thing I wasn't able to fully understand from the Kagi article: how does this solve the problem of "token handoff"? For example, if User A generates a token (from an unlimited search acct) and hands it to User B, whom has no association with Kagi, how does Kagi block User B's access? Or do they just assume it's fine because the token count is capped at a low enough value as to make it unprofitable for me, as a user, to purchase an unlimited search plan and then resell my plan at a lower price (making a profit on volume) by handing out my precomputed tokens to my resold subscribers to use?

It doesn't solve it.

I don't think that there is a need for a technical solution to that, though. In the Kagi example, probably they trust that their users won't do that, and someone could already resell searches this way (e.g. write some kind of proxy). Similarly, an adult can already help a kid get access to stuff they shouldn't. But the point is to make it harder for kids to do it on their own, for their own sake.

It's not computer security, where your system is "as weak as the weakest part". We don't care if a few kids access social media: the goal would be to make it such that the norm, for kids, is to not have social media.
