An anonymous reader writes "I have a roommate that insists on using BitTorrent without taking any kind of precautions. He has an affinity for downloading material that is extremely popular and high-risk. He's received a warning from a well-known media giant in the past about his file sharing, but hasn't been sued. We've recently begun living in an apartment together (with one other person) and share our Internet connection and IP address. If his p2p activity leads to someone attempting to take legal action, could I be held liable? How would our accusers differentiate between our computers if we all share the same IP address? Would they just sue the lot of us?" Some lawyers would certainly like to get a look at everything on the other side of the connection. Has anyone out there faced legal problems as a result of someone else's use of your connection?
