The chinese were the first to censor the internet and media with algo's.
Exerting Control
The Chinese government deploys myriad ways of censoring the internet. The Golden Shield Project, colloquially known as the Great Firewall, is the center of the governmentโs online censorship and surveillance effort. Its methods include bandwidth throttling, keyword filtering, and blocking access to certain websites. According to Reporters Without Borders, the firewall makes large-scale use of Deep Packet Inspection technology to block access based on keyword detection. As Ng points out, the government also employs a diverse range of methods to induce journalists to censor themselves, including dismissals and demotions, libel lawsuits, fines, arrests, and forced televised confessions.
To the degree that Chinaโs connection to the outside world matters, the digital links are deteriorating.
Our friends at CFR wrote a nice little paper about how they do it.
