Germany doesn't. The government just decided not to implement blocking (after arguing about it for years). Anyone (worldwide) who hosts child porn will be contacted by the police and asked to delete it. (When that was tested in January, 99% of the offending sites were gone after four weeks.)

That's why I was so surprised. I only really followed the debate in Germany (that's where I'm from), not in the rest of Europe.

Perhaps, but given their sensitivity you would want to comply or face some difficult discussions with intelligence agencies.

They may not be enforceable by the letter of the law, they aren't quite as "advisory" as the name would imply.
