The recent surge in disinformation targeting gender themes poses a substantial threat to women’s equality in democratic systems. This study investigates the efforts of three fact-checking platforms prominent in Ibero-America (Maldita.es and Newtral in Spain and Chequeado in Argentina) in countering antifeminist fake news. Employing a dual methodology, we conducted a content analysis of pieces published on gender issues over one year and semi-structured interviews with representatives from these platforms. The findings unveil a consistent production of texts addressing contemporary feminist affairs. Disinformers target both the feminist movement and its historical grievances, including gender-based violence. Fact checks emerge as the primary format for combating these hoaxes, with explainers gaining against increasingly complex disinformation narratives. The verification methodology emphasizes consulting official sources and expert testimony. Interviewees acknowledge that there is still much progress to be made in gender-related fact-checking.
