The closest attempt I can think of is status wallets token ranking for dapps. You could burn your tokens to say if you liked something in their listings and that would rank it for others. The issue they hit is when the lists got popular (in like 2018-19) vc funded projects just bought up the supplies of tokens and burnt them to get their project rated higher. So basically Sybil attack and they became unreliable.
It’s the same problem across all decentralised protocols, if it’s cheap to say something you get spam(see email) but introducing costs can just skew it to those who can afford to spam instead (essentially those with an advertising budget).
So there’s been a lot of research on proof of personhood (BrightID/ideas/proofofhumanity) to add Sybil resistance mechanisms so we can do 1p1v across the network. They’re working ok, but the next big step is adding zkproofs so we can anonymise the voting (which is needed to prevent collusion) which clrfund and sismo are working on.
Kleros have an interesting curated register protocol, which seems to work on small scales. Some groups are using it to token rank guy issues to prioritise work and get feedback.
The status blog has some interesting writing around these ideas over the past few years https://status.im/research/
