Federal prosecutors have accused the owners of Megaupload with violating piracy laws, possibly exceeding 500 million dollars in pirated content. One the 13th most popular website in the world, operating as a free file hosting service for any kind of content, Megaupload.com is potentially gone forever.
Megaupload.com staff claims they were always on top of complaints about material that might have been pirated, but for now the service and the content stored within are gone. Currently, there are no answers available as to whether or not the legitimate content stored there will be released.
For users who had previously used Megaupload, some alternatives to the service are RapidShare, MediaFire, DropBox, or Box.net
