The present study explores gender-based violence discourses in social media, highlighting Jurij M. Lotman's ideas of the mechanisms of shame, fear and honor. As an analytical instrument, this model is intended to be used to investigate ways in which digital media are shaping the narratives of collective shame and false confessions, affecting public opinion on women's abuse and gender-based violence. In this perspective, the narrative continues to deal with how media representations legitimate court sphere, ideological conceptions and perpetuate the normalization of violence against women and marginalized groups. By deepening our understanding of how the guilt is manipulated and the collective shame is built, the study aims at identifying the subtle and hidden link between the media discourse and the actual events as they take place, translated into mediated interpretations that shape the public understandings of the relationship between the guilty and the victim, and worsen the feeling of collective shame. Thus, the question is about the role of the media in the formation of dominant ideologies and the reproduction of gender-based violence through their modes of representations. Through the semiotic analysis of critical cases, the sudy will contribute to the comprehension of the mechanisms that social media deploys to shape the public opinion on gender violence, roles and dynamics, and in turn will unveil the path to find potential solutions towards a social revolution.
