And then those who are listed on ORBS complain that the list is being 
used to suggest attacks on those open relays.  While MAPS may not have a 
single list you can download, anyone is free to lookup any IP address and 
see if it is listed, so it is definitely public.

Or perhaps because those who care to use MAPS didn't see any spam from your 
servers in the first place...

I use RBL/RSS/DUL on my home email server.  I recognize that some 
legitimate mail to me may get bounced (I periodically check the logs to 
see what is getting rejected, which is about 1 legitimate mail every 2-3 
months), but that is a price I am willing to pay to avoid spam.  Anyone
I really care to talk to knows other ways to contact me anyway.

My home email account gets about 1 spam per week, while my email address 
at a previous employer (which does not use RBL/etc) gets about 150 spams 
per day.  Both addresses are listed as whois contacts, both have posted 
messages on public mailing lists, etc.  That is why I choose to block
sites listed there, and I suspect that is the reason most people choose 
to use them.  It has nothing to do with your philosophy -- I had no idea
who you were or what your philosophy was until you started this thread.

Nobody forces anyone to use any of the MAPS lists.  At a previous 
employer, we used MAPS RBL for a while until Netcom was blocked.  As we 
were an ISP, many of our customers complained about this so we stopped 
using RBL until we were able to offer the option to enable it 
individually per account and allow each customer to configure their
