What about putting a Javascript confirmation upon form submission that
sets a value:
<form onsubmit="if (confirm(.....)){ [SET VALUE]; return(true); } else {
return(false); };">
In the above line, the [SET VALUE] could set a hidden form field to a
predefined value. The confirmation is a bit cheesy, but I am guessing
spammers don't actually "run " the live page and therefore wouldn't set
the hidden field. And, you could randomize the field for each page
refresh so it couldn't be guessed.

Subject: Re: Help with Form Validation Against Spam
I know that nobody wants to put their site visitors through the trouble
of entering some anti-spam verification code into the form but in this
case I really don't think that Capthca or Math is the right solution.
I would rather just use a regular expression. The reason is that email
newsletter subscriptions are delicate. People are already hesitant about
subscribing and I don't want to make them beg for it.
I didn't think about checking if the first name and last name are the
same, I may try that (and count my losses when/if anybody with the same
first and last name tries to enroll).
I may use Math or Lyla Captcha on other forms on my site though, so
thank you for the links.
