said by Methadras:what is your answer to getting a dmca/mpaa/riaa notification on files that are named to copyrighted material, but the actual data is either not what is described via the file name or is just junk...? since p2p is nothing more than multiple users giving up chunks of data to other peers in a swarm recombining that data from those other sources, then how are the xxaa's knowing what you are getting or serving...?
They complete the download, and play it? How hard is that? Or maybe they can download 10% - 25% and get a checksum signature for that portion downloaded.
In any case, I doubt that they can go before a court with just the title. The judge is going to want substantial evidence of the unauthorized upload.
OTOH, how much evidence is your ISP going to want to see before they TOS you?
It is a legal gamble, for them as well as for you. Only you can decide if the risk is worth the trouble. But a simple email notice isn't much to worry about, in itself. It is just a heads up that you need to re-examine your activity.
