Or there is the digital approach

North Korea demands neighbors spy on neighbors in surveillance push

Authorities are offering rewards and threatening punishments to normalize citizen surveillance and reporting of "anti-socialist lifestyles"

According to a source in North Pyongan province, regional branches of the Socialist Women’s Union of Korea (SWUK) held year-end review sessions starting Dec. 20. The meetings evaluated how well members followed directives from above, including participation in political study sessions and compliance with neighborhood watch protocols.

Officials repeatedly instructed attendees to “keenly watch for behavior that goes against socialist lifestyles.”

“They kept emphasizing that we must raise each other’s awareness and immediately report non-socialist behavior so the enemies’ schemes don’t take root in people’s lives,” the source said.

Grim of course, but there is a flavour of old school totalitarian measures about this. It's a long way from facial recognition or China's social credit system.

And yet...

The UK pandemic debacle was merely one reminder that it is possible to encourage natural informers to indulge themselves when confected virtue is on offer. It's as well to be politically vigilant.

Which of course we aren't.
