Try using a program called "Peer Guardian 2", freely available on the net. This will block many thousands of dodgy RIAA/MPAA/BPI etc websites from contacting your P2P program and identifying you as a file sharer, it also scrambles your P2P programs attempts at connecting to other P2P IP addresses allowing you to file share anonymously (if thats what you might be doing, i can't condone illegal acts

).
I would like to know if passing the information about what you have downloaded onto a third party breaks any part of the data protection act? it seems like virgin (my broadband provider) are doing this with the BPI.
They (VIRGIN) are then sending threatening "cease and desist" letters to certain downloaders or they will have their service terminated!
Is it legal to threaten to or actually terminate a service to someone that has not been criminally convicted of file sharing?
Surely ISP's are contracted only to supply a connection to the Internet and not spy on the particulars of any data transfered?
