The actual provider of the content is not the link. It's what's at the other end of the link, which in these cases is the person claiming to be wronged.
That's incorrect actually. I read the verdict (I speak Dutch), and what happened is that the photos leaked and were uploaded by some unknown person to FileFactory.com and later to other filesharing sites. GeenStijl.nl posted an article saying "hey, Britt Dekker's nude photos are leaked, you can see them OVER THERE".
I don't know how GeenStijl.nl came to know the URL. Got a tip from the person who leaked the photos, I guess.
As someone here said: the case is more nuanced than would appear from the summary, but I don't really know what to think of it.
