"This paper argues for the reexamination of hashtag activism from the theoretical frameworks of liveness and appropriation. Scholarly discussions of online activism have, for the most part, focused on if and how technology revolutionizes social and political movements. Going in a different direction, I contend that scholars should examine how specific mechanisms for participation, such as the hashtag, enable and/or constrain online activism. Using the #BlackLivesMatter hashtag as an illustrative example, this paper argues that hashtags are limited by the digital and social construction of liveness, and are too easily appropriated. The implications of these limitations and considerations for future hashtag use are discussed." (Abstract)
