Suspected Violations by 𝕏 of Article 26(3) of the Digital Services ActTogether with other 8 civil society organisations, Entropy has lodged a formal complaint with the competent regulatory authorities concerning potential violations of Article 26(3) of the Digital Services Act (DSA) by 𝕏 (formerly Twitter). This complaint is jointly submitted by AI Forensics, Centre for Democracy and Technology Europe, Entropy, European Digital Rights (EDRi), Gesellschaft für Freiheitsrechte (GFF), Global Witness, Panoptykon Foundation, Stichting Bits of Freedom, and VoxPublic. Based on research and evidence compiled by AI Forensics, and per the right to lodge a complaint under Article 53 of the DSA, we express our deep concern regarding the use by 𝕏 of users’ sensitive personal data for targeted advertisementsIn response, we call on the relevant Digital Services Coordinators and the European Commission to protect individuals and communities from discriminatory or exploitative profiling that undermines their rights by promptly investigating 𝕏’s potential breach of Article 26(3) of the DSA.
