We use AI to identify, analyse, and act against online hate speech

Welcome to the European Observatory of Online Hate
Meta’s rollback of content moderation in January 2025 coincided with a sustained rise in toxic language targeting women. Our analysis shows that relaxed enforcement may be enabling a surge in gender-based hate online.
In May, we provide an overview of the online hate speech landscape, with a focus on the evolving narratives of Sexism, Antisemitism, Anti-LGBTQ+, Anti-Muslim hate, Anti-Refugees and Anti-Roma narratives.
