During my brief visit in Brussels to participate in the Act on ACTA seminar someone told me a joke. The joke was that Cecilia Malmström not only wants to block websites, but that she wants the EU to take controle over the RIPE database.
The RIPE database is part of a Dutch authority that controls the large chunks of IP-addresses in Europe and parts of Asia. If a government controls it, they have the direct power of terminating entire internet service providers.
Now, it seems that the joke was not a joke, and this is what Malmström wants in order to fight child pornography online.
There is not so much information out there yet, but here are a couple of links:
