Lumen is an independent research project studying cease and desist letters concerning online content. We collect and analyze requests to remove material from the web. Our database contains millions of notices, many of them with a valid legal basis, some of them without, and some on the murky border. The presence of a notice in our database does not indicate a judgment among these possibilities, or that Lumen is authenticating the provenance of that notice or evaluating the validity of the claims it raises.
