Download it and get sued.

As it has gone from VHS to DVD to downloads and pay-per-view, the porn industry, god bless it, has generally been ahead of the curve when it comes to figuring out how this whole digital distribution thing will work.
The music and mainstream movie industries have had to look to adult video to see what their own customer relationships might look like in five years.
But at least one porn director is taking a page from the old-schoolians in music and film (we're looking at you, RIAA) and suing the hell out of prospective customers -- 7,098 of them to be exact.

The cast of 'Batman XXX ... '

According to CNET, producer Axel Braun has filed a federal copyright suit against the alleged downloaders, uploaders, and file sharers. They're accused of aiding and abetting in the mass (and allegedly unpaid) enjoyment of Batman XXX, A Porn Parody.
The director filed in the U.S. District Court for the Northern District of West Virginia. The film was distributed by L.A. and New York-based Vivid Video. So why it was filed out there is beyond us.
"F--- 'em all," Braun told Xbiz, the porn industry news site. "People don't realize that when you pirate a movie it hurts all of the people who work very hard to get it produced--from the cast to the production assistants to the makeup artists...So we are going after every one of them who pirates our content."
