fills out my order form - how to stop
Hey Rick,
It's called a CAPTCHA. Doug Hughes at www.alagad.com has a
pretty cheap CFC that generates CAPTCHA images, or there's
the low-fi way of doing it: premake 100 or so of your own in
photoshop.

I ran into this problem recently. To work around it (at least temporarily),
I made the form action attribute point to a non-existent page. Then, when
the onsubmit event gets fired, I substitute the real action page.

speak.

security. It allows users to only post a form once per form call, and
zeros misuse of forms.
The idea behind this is you create a value, serverside with ColdFusion
and verify this value against a dynamic created MD5 string.

But what's the point for the spammer of doing it? Even if i wanted to
throw away some money on a ripoff online gambling, I couldnt from this

Perhaps it's a way of phishing for yet another email address to spam if

You might set a hidden form variable whose value is the IP of the
Others have suggested a CAPTCHA which would work, but in this case it seems
like you could just return an error if you find any HTML in the comments
field.
I doubt it's a human doing it so this would, I think, effectively derail the
bot.
If you are going to a CAPTCHA you could go simple and see

pornographic and the group was getting quite upset about them. I had
