alt Hacker NewsWhat are some strategies a platform like this can take against spam or influence bots? Tying real life identities to users would certainly limit that(though identity theft and account selling could still happen), but that adds friction to joining, poses security risks, and many people might feel less comfortable putting their opinions openly online where backlash could impact real life.

For many purposes, we need anonymous authentication. I haven't heard about much innovation on that and similar privacy fronts in awhile.
Off the top of my head, a possible method is a proxy or two or three, each handling different components of authentication and without knowledge of the other components. They return a token with validity properties (such as duration, level of service). All the vendor (e.g., Polis) would know is the validity of the token.
I'm sure others have thought about it more ...
We really need proof of soul systems to exist, extended to also have a proof of citizenship. While the proof of soul systems can plausible be done in a decentralized manner, proof of citizenship is much harder, and in my opinion this is one of (the few) things the government should really do.
