Analyzing censorship of the death of Liu Xiaobo on WeChat and Weibo
On July 13, 2017, Liu Xiaobo, China’s only Nobel Peace Prize winner and its most famous political prisoner died from complications due to liver cancer.
The scope of censorship of keywords and images on WeChat related to Liu Xiaobo expanded greatly after his death. Our analysis of WeChat keyword-based censorship shows that after his death messages containing his name in English and in both simplified and traditional Chinese are blocked. His death is also the first time we see image filtering in one-to-one chat, in addition to image filtering in group chats and WeChat moments.
Sina Weibo maintains a ban on searches for Liu Xiaobo’s name in English and Chinese (both simplified and traditional). However, since his passing, his given name (Xiaobo) alone is enough to trigger censorship, showing increased censorship on the platform and a recognition that his passing is a particularly sensitive event.
