You can tell this is the case here by the fact that not a single US agency is listed in the seized banner.
Maybe that's the reason they couldn't seize the domain names, but somehow managed to get the .onion server.
I'm wondering though: why Germany and the Netherlands? Did they host their servers here? Their company is (was?) registered in Belize, hosting servers in Germany just doesn't make sense.
Despite this event, incredibly, Germany and the Netherlands continue to be among the countries with the best civil servants in the world and even those that have a much more liberal policy regarding these issues than other countries.
Of course, this does not prevent the authorities from taking action when justified, but things really need to escalate significantly for that to happen.
