China's social credit score is centralized and not anonymous. So, there's not really much to compare. An decentralized credit score would have you scored by your peers. An anonymized one would only be evaluable when you chose to use it. Could it present some heretofore unimagined dystopian situation? Sure, but the question was whether there was an application, not whether it was a good idea to build it :) Moreover, reputation systems aren't inherently dystopian (or all encompassing like a social credit score, ftm), or we wouldn't have the long standing real-world ones.
