Users play cat-and-mouse with censors amid protests

Word of anti-lockdown protests in China spread on domestic social media for a short period last weekend, thanks to a rare pause in the cat-and-mouse game that goes on between millions of Chinese internet users and the country's gargantuan censorship machine. Chinese authorities maintain a tight grip on the country's internet via a complex, multi-layered censorship operation that blocks access to almost all foreign news and social media, and blocks topics and keywords considered politically sensitive or detrimental to the Chinese Communist Party's rule. Videos of or calls to protest are usually deleted immediately. But at moments of overwhelming public anger, experts said, the system can struggle to keep up.
