With the rise in prominence of live-streaming as a cultural production, a form of socialization, and an economic marketplace, this article is concerned with the ways content moderation policies and community guidelines implicitly foster harmful understandings of gender. Looking at Twitch specifically, I demonstrate through discourse analysis of platform policy documents as well as community discourse in relation to a 2018 update to the Twitch Community Guidelines as to how gender is understood, constructed, and ultimately reinforced through dominant ideological frames. I argue that the sexual politics of Twitch (and other streaming sites) resulting in marginalized and hegemonic patriarchal gender relations is a consequence of more than misogynistic culture but is in fact reinforced through the platform and the enacted policies associated with that platform. This results in cultural, social, and economic disadvantages for women online and is reflective of platform moderation’s impact on larger gendered divides across digital media spaces.
