This is the MedDMO annual report detailing the results of monitoring online platform practices to support the national authorities of Cyprus, Greece, and Malta in combating active disinformation campaigns. This report presents findings from our analysis of the MedDMO fact-check archive (1 January–30 June 2024). We mapped the channels—social media platforms, local news outlets, and other online or offline channels—through which disinformation circulated in Cyprus, Greece, and Malta, and evaluated how each platform’s moderation tools (warning labels, removals, context panels, and community annotations) were deployed in response. These insights will both inform our assessment of the platforms’ Code of Practice on Disinformation reports and strengthen ongoing monitoring of the media landscape across all three countries.
