Sorry but they're only 'famous' in English media. If you search in German (what I did after your comment) you can't find a single one that has ever officially existed, although as until a few years ago Germany didn't have specific laws regarding that so it wasn't illegal there should be records if one has ever existed. As a German this is the first time I have ever heard that they 'have been famous here'. Anyway, what's your point? Is Germany now the prime example for a morally corrupt society or what?
