Why? China does flag people for monitoring 24/7. Is it hard to believe that in China where the party values stability over everything else that they would not have ID people that they feel post / report unfavorably on the CCP as someone to be tracked / watch by a human at all times? The Chinese state security apparatus is quite good and has near unlimited budget and man power.
Also, I have hard time seeing an automated system that deletes someone's account including all data for using the f-word in their password.
