Friday 20 November the UK government presented the new Digital Economy Bill bringing in hardcore legislation against fileshares.

Minister for Digital Britain Stephen Timms announced that Internet service providers will be forced to send cease-and-desist notices to customers they suspect of copyright infringement. The ISPs are then obliged to pass anonymous details of these notifications to copyright holders -- if an ISP refuses, it faces a £250,000 fine.  Film studios and record labels will use these notifications as evidence to apply for a court order to find out the user's name and address, so they can haul users up in front of civil proceedings.
