Caitlin Roper

Caitlin Roper is an Australian feminist activist^[1] and Campaigns Manager at Collective Shout,^[2] a grassroots campaigning movement against the objectification of women and sexualisation of girls in media, advertising and popular culture. She is the author of Sex Dolls, Robots and Woman Hating: The Case for Resistance, published by Spinifex Press in 2022.^[3][4][5]

Roper has campaigned against male violence against women,^[6][7] including pornography and the commercial sex trade, which she argues are forms of male violence against women.^[8][9] In 2014, an Internet user identified as Nader Modgeddi created a social media account impersonating hers and advertised her availability for sexual services.^[10] An investigation by The Saturday Paper's Martin McKenzie-Murray found that the perpetrator was a young American man named Nader Modgeddi.^[11] Roper told the newspaper that "given the nature of my work, I'm somewhat used to abuse and threats from men online".^[11] In 2015, Joshua Ryne Goldberg created a Twitter account impersonating Roper, publishing offensive content and paying to boost the tweets to a wider audience.^[12][13]

In 2022, Roper's book Sex Dolls, Robots and Woman Hating: The Case for Resistance was published by Spinifex Press.^[14] She argues that sex dolls and robots modelled on the bodies of women and girls produced for men's sexual use fuel female objectification, undermine the status of women and girls and contribute to men's violence against them. Roper called for the criminalisation of child sex abuse dolls, arguing that the products normalise and legitimise child sexual abuse, in a chapter in Man-Made Women: The Sexual Politics of Sex Dolls and Sex Robots (Richardson and Odlind, 2022).^[15] Collective Shout has successfully lobbied online retailers selling child sex abuse dolls to withdraw them from sale, including Wish, Alibaba, Etsy, Made-in-China, Shein and Temu, as well as some accounts on Instagram and Twitter/X.

In 2025, Collective Shout published an open letter that called on payment processors to stop processing payments on gaming platforms Steam and itch.io that hosted rape, incest, child sexual abuse and sexual torture games after Roper identified almost 500 listings (see Collective Shout § 2025 Steam and Itch.io game removals).^[16] In response, Roper and female staff at Collective Shout were sent rape threats, death threats, and image-based abuse that turned their photos into pornography and images of extreme violence and torture.^{[17][18][19][20]} Following the abuse, Roper was featured in an article in The New York Times about the use of A.I. including Grok to create violent abuse imagery.^[21]
