During the summer 2001, me and my wife toured Vietnam and we had a great time. For that occasion I set up a little online diary that would allow us to post entries while on the road, to allow our families and friends back home to be able to keep up with what we were doing.
Fast forward to present day: the diary "submit new entry" form is still left on my site, and while it no longer works (it hasn't worked for many years) - it is still one of the most visited pages on my site! It seems the automated spam bots find it and submit crap to it... the crap doesn't end up anywhere to be seen nor is it even stored on the server, but it clearly identifies evil machines! Isn't that a honeypot as good as any?!
So far during September 2007, no less than 309 unique IP addresses have issued a POST on that page..
