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

If anybody needs samples, contact me - quickly. We only retain it for

(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.
