Even if there is no nationwide "social credit score", local governments have been experimenting with an incentive and penalty system for decades now. This is well documented inside and outside of China.
Even the new nationwide law set in place in 2022[1] mentions some of the same practices carried out by local governments:
> There are 14 penalty measures for untrustworthiness, broken into 3 types [...] such as restricting entry in a marketplace or industry, restrictions on holing [sic] positions, restrictions on spending, restrictions on exiting the country, restrictions on promotion to a higher level of schooling, and so forth [...]
The law is so vague that I can imagine in practice it's abused for all sorts of things, such as "causing unrest", "spreading falsehoods", or whatever the local or central government deems to go against their bottom line.
Even sources that try to label this as a myth[2,3] can't avoid mentioning that these systems do exist as localized "pilots". So whether or not this is done nationwide, whether or not a "score" exists for individual citizens, and whether or not they're aware of it, doesn't make this a myth, or some form of Western propaganda. Your statements that all of this is a myth is patently false. Please stop spreading disinformation.
