In this report we provide the first systematic study of keyword and website censorship on WeChat, the most popular chat app in China

In this report, we reverse engineer three popular live streaming platforms (YY, Sina Show, and 9158) and find keyword lists used to censor chat messages. Tracking changes to the keyword lists over the past year gives an inside look into how these applications implement censorship

In this paper presented at USENIX FOCI 2015 we use reverse engineering to provide 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 including criticism of the government and collective action. These results provide evidence that there is no monolithic set of rules that govern how information controls are implemented in China.

This report is an analysis of the types of content removed by WeChat on its public accounts (also known as “official accounts”) blogging platform.
