CS ... I think people asking about songs get moderated just as much as movie requests. The problem is no one really knows what is copyright and what is not. Hundreds of Grateful Dead Concerts are freely available and totally legal (not every concert but a huge number and as long as no one is making a cent profit from them, and a lot of other music and other files are totally legal. Someone recently asked about a programme he had downloaded and couldn't get to work, and some one said HEY PIRACY!!!. but it was a piece of Freeware, he just wanted to know how to make it work!!!
It seems an inquiry about a 50 year old song does not get pounced on with the same venom as the latest Harry Potter movie and I have yet to see a request for an old film Ah yes ... they were all deleted
So not everything is illegal and apart from the legal music, there are photo's, archives of all sorts and so on. The whole thing is way too screwed up ... probably
