raving lunacy - oxymorons for the 21st century

Wordpress uses Askimet as a spam fighting tool. Works pretty good. In your Discussion Settings you can list IP addresses as spam.

This is the WordPress version of Lipstick on a Pig. The spam still shows up and must be deleted manually.
I currently have 2 IP addresses that account for 99% of all the spam that shows up here.

Here is what I would like to have happen. When spam arrives with the blacklisted IP addresses, I would like it to be forwarded to the CAN SPAM folks and bounce it right back to where it came from so that I do not see it, nor do I have to deal with it.

Ideally, after say 100 bounces and forwards, removing the DNS for the IP’s in question, might wake up the network administrators and get them to close off these holes.
Yes I know that the IP header can be spoofed, but you start shutting these assholes down, then we can all go back to bitching about everything else.
