"When TorrentFreak reported that Media Defender (MD) was behind the video 
site MiiVi, they cast doubt on us. Now, in what is surely the biggest
BitTorrent leak ever, nearly 700mb of MD's emails have gone public."

"Just about every aspect of the company's operations on every file
sharing network is revealed in the emails, including their fake eDonkey
server and Soulseek activities, not to mention payroll issues and
discussions about what to eat for lunch."
