Had to get my 2-cents in because my company was a recent victim of
SPEWS. A few months back, our /26 block was listed as part of a /24
block due to a spammer that used to reside on a /26 above us. Since the
only way to contact the SPEWS administrators was through their
newsgroup, I left a post asking to be delisted, and received the
newsgroup equivalent of a public crucifixion in return. The reasoning
behind their refusal to delist us was that as a customer of WorldCom, we
were as bad as the spammers. We've since found a way around the
problem, but I strongly recommend avoiding this list. I've rarely
encountered a more unreasonable group of people.

Excluding the recent issue with the LLDC listing (1280), my observations

match what you have said.

The thing to bear in mind is that they publish an opinion about ISPs
basically. So if ISP A had spammer B on their network for 6 months and
did
nothing, they can expect to get a large swathe of their network listed
in
the opinion list.

I am not SPEWS :)
