The documents do not make "bad social credit" (whatever that means) a punishable cause. There is one clause relating to spread of false information but it specifically says "false terrorism information related to civil aviation safety".
There are two classes of offenders. Air travel and luxury/sleeper/high speed G-train travels are banned; regular trains are not.
The first class of offences pertain to directly violating transport regulations, like refusing to quit smoking on an airplane, forcing one's way onto the runway, or refusing to pay for a ticket even after getting caught riding the train without one.
The second class is credit related and has six categories. The first four categories are mostly targeted at resourceful people who have misdeeds but somehow are not criminally punished. One thing that conceivable casts a wider net is for those that refuse to pay social security insurance premiums or obtain social security payments through false documents. The fifth category is about people refusing to follow court orders. The sixth category about "others" that could be added is more elastic but it did say that changes need to be published by editing the document.
