We use AI to identify, analyse, and act against online hate speech
Welcome to the European Observatory of Online Hate
This report is the fifth in a series providing a quarterly analysis of online harm trends. This edition examines patterns observed in October, November, December 2025.
We examined antisemitic and Holocaust denial content through our dashboard monitoring, analysing how disinformation fuels harmful narratives and assessing the role of platform policies and the Digital Services Act (DSA) in addressing and curbing illegal forms of hate.
In December, 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.
