empornium.us How do they stay up?

Looks like everyones stuff is in there for free download. Mine, yours everyones. Whats the deal? I have noticed that there are even other threads HERE pointing to them as a good place to get free Bit torrent downloads of porn. A lot of them are posting Entire DVD rips, Compulations of entire videos sets form websites etc. How can this be legal? Seem to be almost napsterish to me, you get a file that allows points to a seed someone is hosting from thier local home computer, but is this not touchable for some reason. At this point I just want to understand how it is they are still allowed to offer this service and to see what the other comments here are about them...
