Spain is introducing a new tool aimed at monitoring hate speech and polarising content on digital platforms, Prime Minister Pedro Sánchez announced on Wednesday. The initiative, called HODIO (Huella del Odio y la Polarización), is part of a wider government strategy to improve oversight of social media companies and protect vulnerable users, particularly minors.
Sánchez unveiled HODIO during the inauguration of the first International Summit against Hate and Digital Harassment in Madrid. The system is designed to analyse how hate messages spread across social networks and evaluate the influence of algorithms in amplifying polarising content.
“If hate is already dangerous, social networks have turned it into a weapon of mass polarisation that ends up seeping into everyday life,” Sánchez said. “The digital environment cannot be a space without rules. Today social networks are a failed state,” he added.
HODIO will generate indicators to track the evolution of online hate speech, identify patterns in its dissemination, and provide insights into how platform dynamics contribute to polarisation. The system will process large volumes of public activity on social networks to measure the intensity, reach, and evolution of harmful content. The government intends to use the findings to inform more effective public policies and increase accountability for technology companies.
The announcement comes as Spain seeks to enhance internet safety, especially for children. Earlier this year, Sánchez proposed legislation to ban access to social media for users under 16. The measure would require platforms to implement stricter age verification systems, a response to growing concerns over cyberbullying and minors’ exposure to harmful online content.
European institutions have expressed caution regarding Spain’s approach. The European Commission has reminded member states that national measures to regulate social networks must remain within the framework established by the EU Digital Services Act. Authorities stress that individual countries should not implement rules that exceed EU-wide legislation.
HODIO represents a novel approach to understanding the role of social media in shaping online behaviour. By tracking how hate speech spreads and how algorithms affect polarisation, Spain hopes to provide a clearer picture of digital harassment and develop interventions that can reduce its impact.
The system aligns with broader efforts by governments worldwide to hold social media companies accountable for the content they host. By combining data analysis with regulatory oversight, Spanish officials aim to curb the influence of harmful online content and strengthen protections for vulnerable users.
Sánchez said the initiative marks a step toward making the digital space safer and more transparent, and he emphasized the importance of continued cooperation between governments, tech companies, and civil society in combating online hate.
The rollout of HODIO is expected in the coming months, with data collected used to shape policies aimed at reducing online harassment and ensuring social networks are more accountable for the content they host.
