I have used p2p and bittorrent a lot, and I am concerned about security. Does Peerguardian 2 (from http://phoenixlabs.org/) actually work? It is a program that blocks ip ranges from known ad servers, anti-p2p companies, government, and spyware servers from a blocklist (kind of like outpost's) made publicly. Would not the government already see your ip in the current peer downloading section? I know the program does make your "destination host unreachable" when your ip is pinged, but they could just contact your isp.
Has anyone had the experience of your isp contacting you for downloading or have information about peerguardian?
