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.
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.
Both China and Soviet Union (probably others too but I don’t know), pre-liberalization were your typical socialist state with lots of means to control people, so they did but... but people didn’t engage in much petty crime or gang crime.
Those types of crimes were more or less very unusual. But in those same states today with more tools to control people, petty crime and gang-related crime (as well as corruption but that kind of always existed), are through the roof.
And it’s not like either are soft on crime.
So what has given a rise to that criminal activity which for practical purposes didn’t exist before. Is it opportunity? That is there was nothing to gain from it before?
The reason for this isn't surveillance or the harshness of punishments.
The reason for it was that when there's an easy default roadmap for your life (School -> Gainful employment), you're not going to drop out of civilized society, and into criminality at the age of 15.
It's not that there's more to gain from criminality now, compared to fifty years ago. It's that there's less to lose. Instead of a social contract that guarantees[2] employment, a shitty apartment, and food on your table, if you just go through the motions, it's a dog-eat-dog-every-man-for-himself world. Unsurprisingly, many people find it easier to drop out of that, and make a living through crime.
[1] Without even mentioning the truly mind-blowing amount of low-level, and high-level corruption that the USSR experienced.
[2] Employment wasn't guaranteed - people had to go apply for jobs, have their employment and social records get checked, there was competition for getting into good jobs, etc - but 100% employment was an official goal of the state. This is not the case in either the West, or the East, anymore.
During the chernobyl disaster the USSR kept providing false numbers to the world in order to downplay the significance of the event - to the point of sabotaging the cleanup effort and themselves.
There is no reason to believe the CCP does this to solve the robocalls or phone scams. It would be laughable to think XiJinping and his gangs put this issue on his priority list. The only reason is to locate every individual has a different thought against the government.
