Apparently the rampant reports of the MPAA using a fake site to attempt to catch pirates may not be quite truthful. According to the CEO of MediaDefender, the company responsible for the site, it had nothing to do with any lawsuits, and was not even meant for public use.
MiiVi has nothing to do with the MPAA, the RIAA, or any music or movie studio. It was not even meant to be used by the general public at this time. MiiVi has nothing to do with lawsuits. The original story is a complete fabrication.
