It was basically one page explaining that one violated copyright, giving the file name, the date, and the IP address; then a few pages detailing the appropriate laws, explaining how utterly bad piracy is, and telling you how much trouble you are in. Then there was an invoice for a one time "license" for the episode, and the legal fees which were more than the license. Following that, there was a kind of contract you had to sign, agreeing to accept the license, and in case of repeat violation, agree to pay a much higher fee. If I remember correctly, there even was a filled out wire-transfer form you just had to sign and bring to the bank in the end.
If you didn't accept their conditions, and refuse to sign, then they would go to court, which is extremely risky. You might get exonerated, or you might have to pay a lot more, so in the end I just payed the few hundred euros.
Given that the reason I pirated in the first place was that I'm a student and currently can't really afford to buy the media, its especially frustrating...
But I can see why such a strategy would work on their part.
I wonder how many of those letters they send out and how many people stand up to them in court and what the outcome is of those cases.
Recently, someone argued that their router had a known vulnerability, and the rights holders couldn't prove that their WiFi was not hacked, and that they downloaded the files themselves, so they were acquitted. (http://www.heise.de/newsticker/meldung/Filesharing-Klage-weg...)
In my case, there were two factors that made me pay: First, they were in the right. As annoying as it might be, and whatever my positions on "intellectual property" are, it's hard to argue against that. Secondly, the cable connection belonged to a friend, and I didn't want to expose that person to a couple years of legal uncertainty.
If a cease-and-desist letter is unjustified, or in a grey area, I would definitely stand up against it, because I believe I'd have a good chance in court.
Sounds like the perfect legal defense that an IP address does not identify you.
On top of that I would have used the (firm) German privacy laws to use the discovery process to figure out if they had obtained my (private!) name, address etc in a legal way.
To me this seems like a racket and I highly doubt that the case would have ever gone to court.
I would expect an outcome like this:

And without a ton of money the German state would likely appoint a legal representative.
