I think the great thing about China's censorship bureau is that somewhere they actually track all the falsehoods and omissions, just like the USSR did. Because they need to keep track of what "the truth" is so they can censor it effectively. At some point when it becomes useful the "non-facts" will be rehabilitated into "facts." Then they may be demoted back into "non-facts."

And obviously, this training data is marked "sensitive" by someone - who knows enough to mark it as "sensitive."

Has China come up with some kind of CSAM-like matching mechanism for un-persons and un-facts? And how do they restore those un-things to things?
