LumenData from 2002-, Berkman Klein Center
Lumen collects and studies online content removal requests, providing transparency and supporting analysis of the Web’s takedown “ecology,” in terms of who sends requests, why, and to what ends. Lumen seeks to facilitate research about different kinds of complaints and requests for removal – legitimate and questionable – that are being sent to Internet publishers, platforms, and service providers and, ultimately, to educate the public about the dynamics of this aspect of online participatory culture.
