Or just use a registrar and top level domain that won't respond to the take-down requests. .nz domains, for example, are protected by a rigorous process in a domain (New Zealand) that prevents this sort of thing.
Do you know how far that goes? No doubt it works against any schlub who comes along asking for a domain to be shut down, but would they really stand against it if the US put serious pressure on them for hosting thepiratebay.org.nz?
