Would a website dedicated to providing IP addresses to websites whose domains were seized be seized? Just have a directory on an IP-address-accessed server and you've circumscribed the law. Nevertheless, this law is farking redonkulous. Aren't there already processes for removing illegal content from websites? Surely shutting down domains isn't the most effective way. There must be some alternative, nefarious motive…
I'm not sure of their current status, but AlterNIC and OpenNIC are/were two major non-official name registries.
Then there's .onion and other darknets to consider.
This battle is far from over; we're just seeing the first few open skirmishes at this point. If something this draconian came into law and brought down sites of any major popularity, I wouldn't be surprised to see either alternative DNS infrastructures or even a new torrent-like protocol to provide censor-proof DNS-like services crop up to totally disrupt such stupidity.
