Networked counterpublics and discursive contestation in the agonistic public sphere: political jamming a police force Facebook Page

Drawing from agonistic public sphere perspectives, this study examines the jamming of the Hong Kong Police Force Facebook Page by users from its establishment in October 2015 to March 2016. 203 posts accounting for 96,791 comments were analyzed using a mixed-method approach. Findings showed that the early posts were heavily jammed with three types of counterpublic comments: (1) calls for justice regarding alleged police brutality during the Umbrella Movement one year prior, (2) emotional statements with impolite tone, and (3) accusations of comment deletions by the Page administrators. But, the relative intensity of the three types of counterdiscourses diminished over time. Moreover, despite the extensive use of embedded YouTube videos as counterdiscourses in the comments, there were few URL linkages to Hong Kong's dynamic counterpublic sphere. This study highlights the opportunities and constraints of Facebook's technological architecture for activists and networked counterpublics to challenge dominant discourses in situ.
