Social networks can't be forced to police their services for copyrighted material or block users, according to a new ruling from Europe's highest court. The court said that it could not be forced to these things because that burden would drive their costs up and infringe on users' privacy. The Luxembourg-based Court of Justice of the European Union (ECJ) ruled on a case involving two Belgian companies at odds over copyright infringement: a music royalty collecting society called SABAM and the online social network Netlog.
