Couldn't find anything too specific about this after searching sifttalk, but what is the policy concerning sifted vids that have had their audio disabled by Youtube? Are they dead? I'm thinking most of them should be (esp. music videos). Case in point: http://www.videosift.com/video/Art-of-Noise-Moments-in-Love-Rare-Version , which I declared dead, but which was then resurrected still missing its audio. Do we need a *deaf or *mute invocation!?
