Do P2P blocklists keep you safe?

I think so.  This is an excerpt from an article that I copied from http://torrentfreak.com/do-p2p-blocklists-keep-you-safe/.

Recent findings by researchers from the University of California, Riverside, show that 15% of the IPs people connect to on the Gnutella P2P network are blocked by blocklist applications such as PeerGuardian. Statistics like this do not prove anything about the effectiveness of these lists, however, according to an insider who worked for several anti-piracy organizations, blocklists significantly decrease the risk of getting caught by the MPAA or RIAA.

So in short, you need those blocklist software like peerguardian or protowall.  How these programs work is they download a list of IP’s that is part of the government, schools, RIAA, MPAA, etc so that if they search for you, the program blocks your ip address from them.  However, it is not foolproof.  There is no anonymity on the Internet.

I use peerguardian 2, and I always use it for torrents.  If you live in the United States, it is vital that you run these P2P blocklists.  It is better than nothing.
