Anyway, there are 2 ways to shutdown a page.
The ultimate way, and less usual, is a legal request against the servers where it is hosted, what just would make the page have the trouble to find another home.
The main way is legal request against the PERSON responsible for the page.
Since the MD staff is aware of this, hiding info about them and receiving donations via bitcoins, so they are already being cautious and protecting this site.
Oh, the way i'm telling it sounds they are doing something illegal? Oh my sweetsummerchild, the world is not a playground. If you are here, you know how MD have a very fair policy over licenced content. Even so it don't means the "unauthorized" exposition (of not even licenced works) will not bugs some of greed grumpys in Japan.
