Yes: the DoJ built a case for almost 2 years again MU, and subpoenaed and obtained huge amounts of intracompany email in which MU repeatedly admitted knowledge of and financial benefit from piracy. For instance, when an outsider complained that MegaVideo's hosting of the Showtime pay-tv series "Dexter" had desynchronized audio/video, instead of taking down "Dexter", Kim Schmitz fired off mail saying that fixing the AV problem was a priority.

That's just one of many many instances; see up and downthread for others.
