No we only know about it because Snowden blew up his life to reveal it. That should give you a hint about how this works. China is remarkably transparent about their efforts. The government literally holds classes to explain the social credit system. In the US these efforts are buried for years until somebody risks everything to expose them.
The Guardian and The Intercept both did exactly that (which is why you know about the Cisco/NSA thing by the way). I believe French and German newspapers also did something similar.
