Spam-IP.com is a spam database and tracking project. It uses user input by either a spam submission for or a honeypot to capture spammers info and then display it publicly.
This site is nice, but they need to implement an API of some sort or at the least allow persons to download a copy of the most recent spam events.
Site looks nice and it’s a great idea. Worth a peek.
