At the risk of megadownvoting here... Megaupload never complied with DMCA requests - I made several as part of some research and never received any response. The site charged for access to, and provided advertising around, pirated content. The site paid people (users/staff - it's a fine line) to provide popular content. It went to extraordinary lengths to hide the identity of its operators. Now if people believe that…
Er, was this content that you held the copyrights to? That statement seems to imply otherwise, which wouldn't really be ok (or itself compliant with the DMCA).
