Looks like mass lawsuits aren't just for Germans anymore: The Electronic Frontier Foundation is estimating that some 75,000 people have been sued for allegedly sharing pornographic movies in the US. This revelation comes as part of a new amicus brief (PDF) the civil liberties group just filed on behalf of 500 file sharers, asking an Illinois judge to squash a lawsuit against people accues of sharing videos from First Time Videos LLC, better known under the porn brand FTVGirls. A footnote of the amicus brief states:

"As of January 14, 2011, by an informal count, well (over) 75,000 people have been sued in similar (in some cases nearly identical) complaints arising from the alleged infringement of pornographic movies. This includes 4507 individuals sued in the Northern District of Illinois alone, in nine separate lawsuits. In addition, mass copyright complaints based on non-pornographic movies have also been brought against over 13,500 people in the District of Columbia."

I just wrote a story about lawsuits like these on NewTeeVee, explaining how German rights holders have filed more than half a million of such lawsuits in 2010. It looks like U.S. rights holders are well on their way to repeat these numbers, unless courts step in - which is of course exactly what the EFF wants. The group blogged on Monday:

"Friday's brief is the latest of EFF's efforts to stop copyright trolls -- content owners and lawyers who team up to extract settlements from thousands of defendants at a time. Tactics include improperly lumping defendants together in one case and filing it in a court far away from most of the accused people's homes and Internet connections. When adult film companies file these predatory lawsuits, there is the added pressure of embarrassment associated with pornography. All of these factors can convince those ensnared in the suits to quickly pay what's demanded of them instead of arguing the merits of their case in court."

It's worth noting that not everyone in the porn biz ready to sue the file sharing masses. Pink Visual's Allison Vivas told me recently that she has no intention to sue individuals, and Private CEO Berth Milton even said that piracy is promotion.
