This chapter delves into the significant yet underexplored role of bots—automated social media accounts designed to mimic human behaviour—in the realm of progressive politics, with a focus on their impact within the #blacklivesmatter and #metoo movements on Twitter, two emblematic movements in progressive politics. The chapter first introduces political bots as a sociotechnical phenomenon, followed by a review of existing literature on social bots and their role in politics and social movements. It presents an explorative analysis of the prevalence and influence of bots within the #blacklivesmatter and #metoo movements, highlighting how bots can occupy significant positions within social network structures, thereby affecting the dynamics of hashtag activism. Despite the common association of bots with conservative and populist movements, this chapter reveals their substantial presence within progressive political movements, challenging traditional notions of political engagement and suggesting a complex interplay between humans and machines in contemporary activism.
