If we, is the US department of commerce, the answer is probably yes.
The only operational significance, is that there is no way easy way of estimating in advance the effect of removing valid DNS information from the system, unless you are the administrator of the system concerned (and even then mistakes happen - not when I do it of course<cough>).
i.e. It may be that a nameserver called "ns1.example.com" supports domains in a completely different TLD, like "example.co.uk", which belongs to an important organisation or service.
Okay, so i am not talking about blocking or removing a name server. I am talking of removing that offending entry (like www.abc.com) from the whois database or whereever the central database is mantained.
That said spammers routinely have domains, and nameservers, removed with very little if any damage to legitimate Internet users.
The real question is should we, words don't kill people, people kill people.
Definitely!
