There's a whole industry involved in monitoring torrent downloads and sending out speculative letters to try to get some money. Then there's a whole industry involved in offering to defend these claims. We got caught out by this by (illegally) downloading one movie in Germany. I always heard in Switzerland there's some kind of "piracy tax" included in everyone's internet fees but I don't know how true that is. In Germany, the ISPs are supposed to only give out subscriber information if there's a strong case for criminal activity but it seems they give the details to anyone who asks. I'm told in Switzerland they don't give out the details so easily.
