I don't think that closing down sites is a good idea. It just punishes the innocent users. I don't even think that it will have any good effect at all. Sure, it is depressing that the thief makes money (does he really sell anything?) with somebody else's intellectual property. But is it worth all that effort?? I think sooner or later somebody would have done something like this. The internet is big and the laws are complicated here. But does this really have to shake our community? I don't think so.
