Federal prosecutors in Virginia have shut down notorious file-sharing site Megaupload.com and charged the service’s founders with violating piracy laws. The Associated Press broke the story on Thursday, reporting that the indictment accuses Megaupload.com’s owner with costing copyright holders including record labels and movie studios more than $500 million in lost revenue. Seven people tied to Megaupload.com have been charged and four are already in custody, including the site’s founder Kim Dotcom. Dotcom earned $42 million from the the site in 2010 according to the indictment. Megaupload.com allowed users to upload and share content without any measures in place to ensure files being hosted on the site’s servers were not protected by copyright. The company claims that it responded to copyright complaints as they were received. According to court documents made available on Thursday, Megaupload.com was at one point the 13th most trafficked website in the world.
