    You don’t need blockchain for reputations systems, lol. Stuff like Gnutella and PGP web-of-trust have been around forever. Admittedly, the blockchain can add barriers for some attacks; mainly sybil attacks, but a friend-of-a-friend/WoT network structure can mitigate that somewhat too,

      Slashdot had this 20 years ago. So you’re right this is not new.or needing some new technology.

      Space is much more developed. Would need ever improving dynamic proof of personhood tests

        I think a web-of-trust-like network could still work pretty well where everyone keeps their own view of the network and their own view of reputation scores. I.e. don’t friend people you don’t know; unfriend people who you think are bots, or people who friend bots, or just people you don’t like. Just looked it up, and wikipedia calls these kinds of mitigation techniques “Social Trust Graphs” https://en.wikipedia.org/wiki/Sybil_attack#Social_trust_graphs . Retroshare kinda uses this model (but I think reputation is just a hard binary, and not reputation scores).
