P.S.
 I've garnered over 1 billion unique IP's in my combined list.
Have written (among other things) an online address verification/removal tool.
and a fully automated spam system that returns results faster than a mail
server can finish it's request.
Sadly, it appears that no one is interested in reaping the benefits that such
a system can provide. Rather, they feel it's better to keep something like
this away from other ppl. So that the spammers will have a better chance.

Too bad, looks like I'm the only one whom will benefit from all this work.
