The other good news is that all those blocks have now been either
returned to Aker Kvaerner Group (successors-in-title to Trafalgar
House Group) or returned to ARIN for reuse, as appropriate.  Any
filters you routing people may have put in place to prevent abuse
from those blocks can be - and, please, SHOULD be, removed as soon
as practicable.  The DNSBL entries for them at Spamhaus and SORBS
have already been removed.
As a FYI, that class B appears to have gone totally silent on the spamming front on the 9th of Sept or thereabouts. We were getting ~40 attempts per day from it.

If anybody needs samples, contact me - quickly. We only retain it for about two weeks. Spams all referencing www.dnt.opt.listaudit.biz (resolves to 141.152.34.207, apparently Verizon, also blacklisted as being part of Empire Towers)

It's still listed on SPEWS.

I killed our manual blacklisting.
