I don't believe there would be a legal basis for taking down a site cataloging metadata about files Laws can be changed. The copyright cartels have the money and political connections to change the law in their favour. We have seen them do it before and they're going to do it again. Torrent sites (like The Pirate Bay) are essentially just that (sites cataloguing metadata about files). They have not be immune to legal troubles, and they are certainly not "beneficial to copyright holders". You're essentially describing current torrent sites. We have them, they are very valuable and useful. They work well enough. However they can (and are) shutdown. We need better.
