Recent studies on internet politics in China have gone beyond the once dominant control–liberalization perspective and directed intellectual attention to the varieties of online activism. Based on extensive in-depth online ethnographic work, this project explores the pluralization of online expression in Chinese cyberspace. Following a constituency of internet users who identify themselves as the “voluntary fifty-cent army,” the paper explores how these users acquire and consolidate their identity and combat criticism that targets the authoritarian regime. Analysis of the confrontational exchanges between the “voluntary fifty-cent army” and their opponents suggests that a perspective that goes beyond state censorship and regime-challenging activism is required in order to gain a better understanding of online expression in China. Close examination of why and how internet users may voluntarily defend the authoritarian regime also reveals how the dynamics in online discourse competition may work to the authoritarian regime's advantage.
