The commies will have a whole bureaucratic apparatus devoted to ferreting out stuff in print and audio/ visual deemed inappropriate by the party big wigs.
Whats wrong with the informal system that they have now? Perhaps its too efficient.
They are just chewing at the edges now. Get a book off a library shelf here, blacklist a movie there. All in the public arena. Where it gets serious is when they start kicking in doors in the middle of the night and check what you are reading, watching and listening to. They will need a huge bureaucracy for that. Loads of paper work to stamp. Reports to write. Party officials to brown nose.
