To try to contribute some real discussion of the actual content of the article, the data revealed in the database is impressively organized, almost indulgently futuristic in its graphic design choices, and the way they source photos in particular is quite resourceful. Anything from immigrations customs photos to photos of foreigners taken from traffic cameras, markets and businesses. There's extensive records of the types of locations people travel to, that seems to use facial recognition in cameras to put together a complete linear record of everywhere a person goes. Other interesting details are keeping track of subjects people have studied, and attempting to map out their social relationships, if they're from "key countries" or might in any way be associated with political activism that they want to monitor.

It looks like this one might not have actually been used and it seems like the biggest lesson that the example demonstrates is that it's just one of many tool sets in a sprawling surveillance ecosystem and there's a bunch of private companies that vie the business of police and other government institutions across China. That sprawl makes leaks like this one more possible.

Sometimes it said that "none of this is a surprise", but I think revealing details in specific ways turns it from a slogan into a concrete reality, and gives a sharper picture of the causality and the capabilities, which levels up our ability to understand in ways that aren't appreciated when it's just spoken about as a generality that we all assume to be the case.

The one thing I would personally flag is how frequently people were sarcastically dismissive of the idea that Tiktok was doing anything useful with this data. But given how extensive and opportunistic their aggregation of data is to profile foreigners, it's easy to see how, say, mapping out the global support networks of democratic activists sympathetic to (say) Taiwan, could bolster and empower them to act through their extradition partnerships and be part of the data that could potentially even support a hot war in Taiwan.

I use Tiktok as much as the next person, and go through cycles of installing and uninstalling it from my phone, but I didn't think but shared cultural exercise of young people from Western countries sarcastically bidding adieu to their Chinese spys was coming from a particularly well-informed place. And when the data is laid down in the concrete way it's harder to mentally inhabit the contradiction of (1) there's no surprise here and (2) there's nothing to worry about.

There was a time 20 or even 10 years ago where none of this would be controversial (that i,s the significance of reporting on a topic like this) but in 2026, at least in some spaces, it seems practically contrarian.
