I have several sites that are getting hit with form spam. I have the script
set up to capture the IP address so I know from where they come.
I see that a lot suggested CAPTCHA, I don't like those either.
The IP solution will give you a constant maintaince problem unless you
save the submissions in database and look for similar postings, then
blocks the IPs. Or just block them right away if they suggests the usual
sheiitee like 400 euro casino rewards etc...
What I've done to fix those issues when I had them was to set a session
var on the frontpage of the site and check on that. If it doesn't exists
when the user enters the page with the form, then I tell them and just
don't show the form. Of course the clever programmer can create a script
that first goes to the frontpage, then the form page, but so far I'm
pretty happy with the solution, no spam for 3 years :-)
