[ppml] /29 limit for ARIN SWIP whois

OK so I guess let me summarize the points of view:

1) SWIP is a valuable and much-needed tool that allows 
network administrators on the Internet to quickly find and
report spammers, and other network miscreants.  The current
limit of /29 is obsolete since lots of entities today are
assigned /32s under DSL, and that does not allow for disclosure
of every entity assigned an IP address.

2) SWIP is an evil thing that allows my competitors to 
rape me of my customer base and spam the hell out of

I think it's pretty clear that David Divins is in the #2 camp.
My comment to this is that I think it pointless to set policy
to make the #2 camp happy.  They won't be happy until the entire
Internet is just one big anonymous network that allows spammers,
child predators and other miscreants to wreak havoc with no oversight
or any way to track them down.

It is pointless to make the claim that a single technical and abuse 
contact is all that is necessary for a netblock assignment of
tens of thousands of IPv4 numbers, and potentially millions of IPv6
numbers.  That is the thrust of the "I provide valid POC for my
netblock, and my customers are none of your business" people. A single
POC for that many entities merely means a single mailbox that
is overflowing with complaints that are ignored.

I think we ALL have had the experience of sending a spam complaint
to abuse at aol.com and seeing how useful it is to getting the spammer
shut down.  That's the morally bankrupt result of the #2 camp logic.
So please, let's ignore their input on SWIP policy.  If we
mandate /32 SWIPS they are
just going to ignore them, the way they are currently ignoring
/29 SWIPS.  So, to hell with them.

For the rest of us who have a modicum of responsibility, in the
#1 camp, clearly SWIPS aren't doing the job.  I will point out that
they aren't even doing the job for the RIR.  If they were, then
the RIR would not allow people to submit spreadsheets and such
as evidence of utilization.
