And then the CCP looked at what the CCCP did, thought "that's cute" and optimised it until they'd invented the social credit score. It turns out digital is the way to go for scale.
I get where you're coming from, but I think it's important to keep in mind that there is no centralized score for Chinese citizens, and that such claims are often sensationalized. [1] However, I'd agree that China is a good example of high degrees of surveillance.
TBH this doesn't seem much different than what western credit warehousers (e.g. transunion/equifax/experian) do.
If the west had a creditscore, mine would be very very low. I am banned on almost every social medium. C, FB, insta, tiktok, reddit, google and more. Its pretty tough sometimes to survive on the internet without having access to all. (Although most still have read access)
