spamhaus drop list

Is there a competing droplist, that can be compared against Spamhaus's
droplist?  That seems like an extraordinary claim, so I'm not satisfied
with the evidence provided.  Is this not the best droplist?

I suggest you avoid spamhaus, MAPS, and SORBS. They are really spammers
in disguise, using blacklists to harm their competition while presumably
letting their own spam through. We know they have used trust of the
anti-spam community to list-wash spam-trap addresses.

See add the IADL pages
on Paul Vixie and MAPS.

You might also look at
Levine, long head of the Anti-spam Research Group, was also unmasked as
a spammer.

Fred Baker <fred at> is on the ISC Board of Trustees, and is a 
Vixie supportor.
