Here's a thought.  Would it be possible to set up a process where
ARIN, as
part of reselling IP addresses, either issues a certificate of

not the
old evil spammer, or ARIN publishes a list of IP assignments that can be
used by ISPs to provisionally remove them from blocked lists?

I sympathize with the original poster, it's sort of like buying a used
car,
only to find out the previous owner was the drunk driver who ran over
your
next door neighbor's dog.


I used to run the AHBL and ARIN used to contact us when they recycled IP
space.  We always removed when contacted by ARIN.

ARIN hasnt contacted us for this since i've been involved with the ahbl
for ~5 years.
just a FYI.
