I wish "them" (whoever "they" are, looks like a guy in Germany) good luck. According to german law the development (I assume "manufacture" and "development" is the same for software?) of such a DLL (with the intention of distribution) would already be illegal, so regardless where the file is hosted, the creator might be responsible. Probably not a criminal offense, but paying damages to the music & movie industry could be even worse.
Circumvention Devices and Services
Â§ 95a (3) German CA, which is also copied nearly word by word from the Copyright Directive, bans certain preparatory acts relating to circumvention. It is prohibited
* to manufacture, import, distribute, sell, rent, advertise for sale or rental and possess for commercial purposes devices, products or components,
* and to provide services
* that are
o advertised for the purpose of circumvention, or
o have only a limited commercially significant purpose or use other than to circumvent, or
o are primarily designed for circumvention.
