The music industry trade group RIAA has added to Megaupload and owner Kim Dotcom's woes, filing a new civil lawsuit.

Megaupload was shut down two years ago after a U.S. raid, and Dotcom was arrested, as well. At the time, the site was bringing in over $25 million per year in ads, and over $100 million per year from premium account subscription fees.

As part of the suit, the RIAA has accused Megaupload of "allowing users to engage in rapid, unrestricted downloading of popular, infringing content."

The RIAA has also been providing the media with a data sheet that shows a drop in piracy since the site shut down, thanks to "an analysis by the RIAA of third party-provided data." These "facts" have often been heavily skewed in the past, and likely do not take other factors into account, like the rise of Spotify and other unlimited streaming services.

Last week, the film industry trade group MPAA filed a similar suit against Megaupload.
