I'm currently using utorrent as my p2p application and was told by a friend that I should be using an IP blocker like PeerBlocker to block certain IP's that track what you are downloading. He is actually a Windows user and after a quick google search I have found that PeerBlocker is not available to mac users. As a result I have downloaded Peer Guardian and have to say I'm totally confused as to how to use it and what "lists" I need to have setup. I just wanted to know of anyone could help me out either to 1) figure out how to use PeerGuardian and explain the list issue or 2) recommend an alternative to PG. I'm aware some clients like Transmission have a built in blocker, does anyone have any experience with that? Thanks in advance guys!
