The Infinite Brief

The social credit system is a collection of blacklists, of which there are more than a dozen at the national level.

Each list is based on similar offenses — such as misbehavior on planes and trains, or failing to abide by a court judgment — and determines the punishments people face, from throttling internet speeds to blocking loans.

While it’s not made clear which list has had so many plane and train trips blocked, a former official, Hou Yunchun, is quoted as saying the system needs to be improved so “discredited people become bankrupt.”

The court publishes the names and ID numbers of debtors on its website. They are banned from plane and high-speed train travel, and can’t stay at four and five star hotels, send their children to expensive schools, book cheap hire cars, or make luxury purchases online.

Some provinces play a recorded message when someone tries to call a blacklisted debtor, informing the caller that the person they want to speak with has outstanding debts.
