History
Roper has campaigned against male violence against women, including pornography and the commercial sex trade, which she argues are forms of male violence against women. In 2014, an Internet user identified as Nader Modgeddi created a social media account impersonating hers and advertised her availability for sexual services. An investigation by The Saturday Paper's Martin McKenzie-Murray found that the perpetrator was a young American man named Nader Modgeddi. Roper told the newspaper that "given the nature of my work, I'm somewhat used to abuse and threats from men online". In 2015, Joshua Ryne Goldberg created a Twitter account impersonating Roper, publishing offensive content and paying to boost the tweets to a wider audience.In 2022, Roper's book ' was published by Spinifex Press. 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 '. 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 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. Collective Shout published an to payment processors signed by global authorities in the anti-violence field, including Detective Inspector Jon Rouse, who dedicated his career to rescuing children from sexual abuse, and Professor Michael Salter, professor of criminology, director of Childlight East Asia and Pacific Hub. Gamers around the world targeted Roper and female staff at Collective Shout, threatening to rape and murder them, creating image-based abuse by turning their photos into pornography and images of extreme violence and torture. The abuse was condemned by United Nations Special Rapporteur on Violence against Women and Girls Reem Alsalem, who described it as “the most serious form of online violence against women human rights defenders I have seen in a long time”. Following the abuse, Roper was featured in an in The [New York Times] about the use of A.I. including Grok to create violent abuse imagery.
