In this paper presented at USENIX FOCI 2015 we consume reverse engineering to provide a view into how keyword censorship operates on four popular social video platforms in China: YY,9158, Sina expose, and GuaGua. We also find keyword surveillance capabilities on YY. Our findings expose 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.
