Social media platforms generate huge profits from free user data. Twitter and other social media sites benefit additionally from the labour of volunteer community managers whose efforts to moderate misogyny and sexism online are often unwanted, punished, and viewed as censorship, uncivil behaviour, or themselves forms of sexism. Hashtag movements like #ThisTweetCalledMyBack reveal a growing labour consciousness on the part of these volunteers and an awareness of their role as an emergent formation within this ‘new economy’.
