You can click, but you can't hide

"You can click, but you can't hide" is an advertising campaign run jointly by several international associations, most notably the Motion Picture Association of America (now the MPA) and the GVU, as part of the larger "Respect Copyrights" campaign against peer-to-peer file sharing of motion pictures. The associations have long alleged that Internet file sharing, or maintaining a file sharing tracker, network or search engine, constitutes copyright infringement since the practice hurts their revenues.
