Unstable operation coming soon...
"the stable operation of the Internet's unique identifier systems" has been possible for many years because it's possible to discover who is (ab)using any particular registration. And contact them if necessary for operational purposes.
Changing this will make illicit or ham-fisted operations much harder to stop. It will be ironic if EU privacy rules make criminal activities easier to get away with.
Don't they need to get all registrants to sign a waiver?
