With P2P it just depends what you are downloading really, how popular the content is etc... and what kinds of encryption your client supports.
Bittorrent, uTorrent and Azureus work fine if the conditions are right, you should be using Block List Manager which will generate a blocking ipfilter.dat to protect yourself to some extent... read up on it.
Newsbin, Newsrover and Newsleecher are all good Usenet clients, as for services, most of the top ones will be fast when the conditions are right, Giganews, Astraweb and Hitnews.eu...
There are copyright agents/agencies looking for people uploading copyrighted material, this is why you have to be careful, KC will cut you off if they are notified by any of these agencies, and KC may charge you to get reconnected. However I doubt a fine will be charged given the small scale of the infringements.
It has been proved before by people, and ISPs who actually protect their customers that an agency handing over an IP, a time and the name of a file which was apparently being shared isn't enough proof, especially on KC given that they use DHCP for assigning IPs - theres too much room for error and false reporting. There are people who have been disconnected by KC who haven't downloaded or shared any material

To the mod... I don't know what was mentioned in the thread earlier, but nothing in this post is over the top...
