Just think about it, why should the RIAA be able to sue someone simply because he or she pays the bills for the internet connection? They need at least a little more than that.
And it looks like this defense is working:
“This month, the inability to prove who actually did the file sharing caused the RIAA to drop a case in Oklahoma. The same defense has worked in a California case as well. As soon as the RIAA realized the person was using this type of defense, they dropped the cases, rather than lose and set a precedent showing they really don’t have the unequivocal evidence they claim to possess.”
Anyway… just reset your wireless router if you receive a letter from the RIAA or MPAA….
