Funny enough, for them to really make it dystopian, they had to add in features that would almost certainly never be added in an IRL version - e.g. showing you who “rated” you, asking you to rate every single interaction, having cops/petty bureaucrats be able to “punish” your rating on a whim just 'cuz (that would probably be reserved for rather higher-ranking people, because they don’t want their toy taken away if too many low-ranking ones abuse it, which of course they would).
I still maintain that a true crowdsourced social rating tool would be a GREAT way to weed out narcissists and similar personality disorder types, because they rely on being able to drift from victim to victim.
Yes, you would need to build in guardrails and create all kinds of trust webs to make it very, very difficult to “buy” trust (or blackmail people to avoid being dinged by a malicious group), but those would have pretty obvious “fingerprints”, 99% of the time. You wouldn’t want to 100% rely on it, but it would be really good first-glance way to see if there’s a huge disconnect between a first impression and what people are saying about someone that have interacted with them over a long period. Kind of like a Rotten Tomatoes score, or, y’know, a credit score. If you pick the right metrics, you can get a pretty good idea of what something/someone is going to be like.
