A court in Germany ruled on Thursday that RapidShare must implement a system that proactively filters user uploads in order to prevent the illegal sharing of copyrighted content. Like Megaupload, which was shuttered earlier this year, RapidShare allows users to upload large files and share them online. The service has become widely known for hosting copyrighted software, music, movies and books that are then shared illegally on forums, blogs and a variety of of other websites. Following verdicts in three separate cases filed by two book publishers and an group representing music publishers called GEMA, the firm has been ordered to take a more active role in preventing infringing content from being uploaded to its servers, TorrentFreak reported. RapidShare has not yet stated whether or not it will appeal the decision.
