The Email Wars

Not sure if anyone else has stumbled upon this venture from UnSpam and a few others but it is an interesting site and operation looking at email harvesting, comment spam, domains involved, etc.

About Project Honey Pot
Project Honey Pot is the first and only distributed system for identifying spammers and the spambots they use to scrape addresses from your website. Using the Project Honey Pot system you can install addresses that are custom-tagged to the time and IP address of a visitor to your site. If one of these addresses begins receiving email we not only can tell that the messages are spam, but also the exact moment when the address was harvested and the IP address that gathered it.

Very interesting system. I will need to keep my eyes on this. As an ESP I would love to be able to search it by IPs and client domains to see if any clients or prospective clients are involved. Would be a great way to vet new clients before taking them on, as well as a way to audit their practices every so often to look for offenders.
