Spammers are slow, but sooner or later they'll use redirectors
everywhere to bypass SURBL.  I don't see the relation between
zombies and SURBL, zombies are used to send spam, not to host
spamvertized sites.  Or are you talking about zombies used as
redirectors, are we already at this point ?

I found neither nina.18.to nor 18.to in multi when I looked
for it.  Today http://nina.18.to is http://Opt.To/notfound.htm

Opt.To offers "free subdomain name redirection service and ads
for your site".  Whatever that means.  AFAIK the automatical
procedures won't list subdomains of a SLD as long as the SLD
is not a "two level ccTLD".  Maybe you could add redirectors
like 18.to to <http://spamcheck.freeapp.net/two-level-tlds>

Otherwise I don't see how you could catch the next nina.18.to
if it's reported indirectly via SC as spamvertized site.  Bye.
