If you have a web site with its own domain, and you’re sick to death of spam, and you can’t make it down to Boca Raton to leave a flaming bag of dog poo on a spammer’s doorstep, you can still fight back.
Project Honey Pot is asking webmasters to install their open-source software somewhere on the web site:
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.
Cute, huh?
