That's not true, man. People used to do that, but then the government got smart about it and that's why they banned megaupload and other file2sharing sites. I think I heard that piratebay got closed down too.
government doesn't give a shit about these stuff. the real reason why sites like Megaupload were shut down is because of DMCA. in other words because of copyright laws. sites like Megaupload were a place for people to share copyrighted material such as Hollywood movies and when you mess with big companies like that which lose millions they shut you down.
