Isn't it more like criminals or serious offenders can't fly? Will you allow a person who can possibly hijack the plane?
As pointed out in another comment : "Other infractions reportedly include smoking in non-smoking zones, buying too many video games and posting fake news online."

There are also designated non-smoking zones that are not due to immediate (as opposed to long-term) safety concerns.
The "buying too many video games" line came from the gamification aspect of a social network owned by a private enterprise and has nothing to do with the government scheme. And even they have backpedaled from that claim:
"Hu Tao, Zhima Credit’s general manager, paints a different picture now. She says the app doesn’t monitor social media posts “nor does it attempt to measure qualitative characteristics like character, honesty, or moral value.” Zhima Credit is not a pilot for the social credit system and doesn’t share data with the government without users’ consent, she says."

And the "posting fake news online" line actually refers to "spreading false information about terrorism" which quite a bit more serious.
Once you've established that you're not pursuing the truth your words are only poison/noise that harms the group of us who are trying very hard to figure out what is true.
