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.
I highly recommend as many folks as possible join the fight against spam. Project Honey Pot provides some simple ways to assist in shutting down spambots.
