I was sort of joking a bit but I do know that german node operators block some traffic. However, it's on a purely notice-and-takedown basis, which is the DMCA of germany but more broadly applicable; if you are made aware of illegal activity on your network you must stop the activity and take reasonable measures to prevent future abuse. They can also fall under the network operator laws in which case they are not responsible for the traffic at all but I'm not sure if that is applicable to tor nodes or not.
