You refer to Ron Guilmette, one of the smartest cookies in the
business to whom the world owes him a lot.  For various reasons legal and
personal he has felt he must cease list deletions; this may be 
temporary and as a reasonable person he will be open to discussion on
this point when the right moment arrives, I am sure.   Anyway use of
his list is voluntary, and recent traffic on Spam-L indicates some of
his users whitelist those listed who have a legitimate story to tell.

As for "what is a member to do with permanantly blacklisted IP space?"
the issue is comparable to what is America to do with polluted land
sites.   Before buying land one must perform due diligence, or one
is sucked into the superfund cleanup morass.   Those getting (and
dispensing) IP address space will have to add to their checklist
whether the IP address is polluted.  

Of course as always the best action is prevention.  I have carefully
studied this issue and personally believe that spamming can quickly
and easily be solved, within days, without lasting collateral damage.
I invite those interested to view and comment upon a draft statement on 
this subject at <>.  I add that since
composing this draft I am very pleased to see ICANN has begun to
rise from its torpor on the simple (and critical) matter of attaching
consequences to actions. (Reference
