Every Rose Has Its Thorn: Censorship and Surveillance on Social Video Platforms in China

Abstract

Social media companies operating in China face a com-plex array of regulations and are liable for content posted to their platforms. Through reverse engineering we pro-vide a view into how keyword censorship operates on four popular social video platforms in China: YY, 9158, Sina Show, and GuaGua. We also find keyword surveillance capabilities on YY. Our findings show inconsistencies in the implementation of censorship and the keyword lists used to trigger censorship events between the platforms we analyzed. We reveal a range of targeted content in-cluding criticism of the government and collective action. These results develop a deeper understanding of Chinese social media via comparative analysis across platforms, and provide evidence that there is no monolithic set of rules that govern how information controls are imple-mented in China. 1
