I realize my first comments is not as detailed as it should have been, I've expanded in the comments.
Black mirror is same vein, but different concept:
Getting loans, buying cars, via a single reputation score is different than giving people a tool to curate the content they wish to consume.
By having access to a "user's reputational history" across multiple sites, you can see where their reputation is coming from. Then you as a consumer of internet media, can choose what site reputation to put value on. Letting you curate and avoid toxicity, or live in your echo chamber if thats what you want.
Its like asking a couple friends if they'd loan their weed wacker to the new guy down the street, they say he acts kind of shady but has always brought back their garden tools. Same thing. You ask users of a couple sites how this other user has acted. They say he made some jokes, but also had some valid points here and there.
We don't then say, oh they made crude jokes, charge them an extra $1000 for rent.
