CPP police always know the small towns of the most robocall farms and phonescam bases. The reason they do not stop those is because local polices take share from crime money, which also contributes to local economy.
If the CCP gang really wants to stop robocalls and phonescams, they only need to send a task force team from the central agencies. Then they can close all the roads around those small towns and shut down all the phone towers, and then capture all the criminals in a few days. There is no need to use AI for this kind of stuff.
Again, it is simply laughable to think Xi's gang care about robocalls and phonescams. They have too many other things to care about.
If they really had total control, having too many other things to care about wouldn't be a problem. After all, they'd totally control those other things as well. But that "task force team from the central agencies" probably has its hands full securing the little control they have.
Given that they do not have total control, things like combating robocalls and phonescams need to be handled by more mundane countermeasures, like adding bureaucratic requirements to the phone number registration process.
Those people are also able to introduce legislation.
It’s laughable to think everyone in a China thinks the same.
Take the Pooh Bear jokes about Xi. He'd love to be able to stop them, but he can't. There's a limit to how total the government's control can be. And with China's capitalist liberalisation, scams and fraud become more attractive, and possibly harder to track down.
