They only seem to do that if there is a website associated with the
spam.

Which there was in that case, and is in this case.

My complaints were against a spamhaus that registers hundreds of
domains as "non-trading" then uses these to temporarily house spamsites
for third parties. Nominet looked at a couple of sites and concluded
that the spam does not spam the services of the registrant therefore
NFA.

Huh!
