An Archive of Social Media Platforms’
Content Moderation and Legal Policies

The Platform Governance Archive (PGA) is a data repository and platform that collects and curates policies of major social media platforms in a long-term perspective. When have YouTube and Instagram introduced hate speech policies? How have misinformation policies changed over time? With the help of the archive, researchers, journalists and the public can answer their questions on how platforms order and govern communication and interaction in our societies, and hold those powerful new institutions accountable.

We collaborate with the Alexander von Humboldt Institute for Internet and Society (HIIG), the University of Groningen, and Open Terms Archive for the curation and collection of the policies.
