I was having this problem when spammers were going to MY WEBSITE and sending spam on MY FORM to ME. It was driving me insane...sometimes 20 a day. Yes, there was a captcha on the page and also my email address was heavily enkoded.

First thing I did was to google my email address and see where it came up and asked whoever to remove it from where ever.

The next thing I did was to find a little javascript thingy that would provide me with their isp address along with the form. Then I went to one of those international whois sites that tell you where the computer is...usually in my case China and Indonesia where they chop off your hands or something terrible if you are a spammer. I would forward all the information I had to whoever the server was...and in a VERY short time, it stopped completely.

Now I just have to get over the guilt of a bunch of handless spammers and get on with my life!
