the thing about this is, P2P is very complicated to monitor, if we're talking small scale then it's much easier, but they're trying to monitor the net, so that's not a simple task. The trend now a day is they uses bait to fish people. What they do is they would release the file themselves to get people in the pool and monitor those files only. Makes it easier to track/watch/catch, so the key here is a reliable source, this is why people always want to be in a pivate group, much safer and chances of them unleashing tracking files on you is much less. Peersgardian does eliminate some of the IP range, but it's quite annoying.
