...one more idea for fountain's what-if future.

What if they only pay if you put in information about yourself or access to your phones' permissions? Age. Location. Income. Net worth. What if they pay more for certain niches?

All fields would be optional to enter, and optional to verify, but doing both would change your earnings multiplier.

Podcasters can likely earn waaaaay more if they know their audience demographics.

I think that could be the money shot here, cause that approach solves the sybil attack problem and lots of people don't really care about privacy.

What would happen is the total audience size can be measured, and then the users who don't care about privacy would enable making assumptions about the balance of the audience who do care more about privacy.
