Resumen: The multiple interconnections given by social media have opened up the possibilities to people to organize themselves around the feminist movement demands. In this article we present the results of a digital ethnography, where we seek to understand the relationship dynamics that are established in a group of women on Facebook around mutual care, delving into the role of this tool in the generation, obstruction or maintenance of spaces. The main conclusions suggest that: a) the online tools allow to create and to maintain thematic relational spaces of interest to the feminist movement; b) the online group analyzed supports the exercise of care among its participants; c) the relationships around care go beyond the online social network, materializing itself in hybrid spaces; and d) the interactions on the platform by the participants reproduce patriarchalized relationships and also offer concrete options for their confrontation, in a constant game of reproduction/subversion.
