A Dallas federal court has ordered file-swapping site LokiTorrent.com to shut down and provide Hollywood lawyers with access to its full server logs, including data that could expose hundreds of thousands of people to copyright lawsuits.

The Motion Picture Association of America said Thursday that it had won a quick court victory against LokiTorrent, and was launching a new round of actions against other online piracy hubs. The data provided by the onetime file-swapping hub would provide “a roadmap to others who have used LokiTorrent to engage in illegal activities,” the trade group said.

Hard numbers on the site’s traffic are hard to come by. However, according to researchers at the Delft University of Technology, LokiTorrent was responsible for more than 800,000 downloads in the month of October alone.

MPAA executives said the information could “quite possibly” lead to lawsuits against individuals.
