"The majority of scholarship on platform governance focuses on for-profit, corporate social media with highly centralized network structures. Instead, we show how non-centralized platform governance functions in the Mastodon social network. Through an analysis of survey data, Github and Discourse de ... veloper discussions, Mastodon Codes of Conduct, and participant observations, we argue Mastodon’s platform governance is an exemplar of the covenant, a key concept from federalist political theory. We contrast Mastodon’s covenantal federalism platform governance with the contractual form used by corporate social media. We also use covenantal federalist theory to explain how Mastodon’s users, administrators, and developers justify revoking or denying membership in the federation. In doing so, this study sheds new light on the innovations in platform governance that go beyond the corporate/alt-right platform dichotomy." (Abstract) more

"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) more
