AIUI, and i'm no expert, it would have to be absolutely massive. When someone put up a banner and burned some tires in Beijing the other day the CCP was blocking the word "beijing" itself on social media for a time. Their level of control is unrivaled.
Is that evidence of awesome control or lack of it? Seems like blocking a word like Beijing because of a single event is over-blocking on a staggering scale; it communicates absolute terror of the populace that results in astonishingly over the top decisions.
