This report provides an overview of the policies and procedures for addressing terrorist and violent extremist content (TVEC) across the global top 50 online content sharing services, with a focus on transparency. It finds that only five of the 50 services issue transparency reports specifically about TVEC, and these five services take different approaches in their reports. These services use different definitions of terrorism and violent extremism, report different types of information, use different measurement and estimation methods, and issue reports with varying frequency and on different timetables. The low number of reporting companies and the variation in what, when and how they report make it impossible to get a clear and complete cross-industry perspective on the efficacy of companies’ measures to combat TVEC online and how they may affect human rights. This situation could be improved if more companies issued TVEC transparency reports and included more comparable information.
