Minimising Form Builder form spam (without using captcha)

Client is getting hit every so often with Form Builder form spam, perhaps a handful a day (and then nothing for a while).
A typical example is attached.
I don't want to use captcha.
There is a
very old thread about this but I wondered if anyone had any good ideas on how to minimise form spam?
(When hand coding PHP forms on non-CMSMS sites (what?
) I normally just disallow any submissions that include
http:// (link) text which works well as most form spam includes a link).

Since you only have a name, email and message field, you could try
Gbook

On a similar note, create a field called URL (spam-bots just can't resist
) and use jQuery to hide it (if you set it to hidden in CSS, it might be caught... dunno) ... Reject the form if you find anything in the field.

Jos, thanks but looks like Gbook is for displaying entries on the website - not what client needs - they need a form which results in an email to them.
Wishbone, thanks for posting the link to the other thread - I used that technique to add a new URL field and I have hidden it with CSS. FormBuilder rejects any submission where that URL field has anything in it using regex. All set up and working - let's hope it reduces the spam.
Thanks again.

I use a field that must have an exact value. e.g. write the sum of twelve and two in characters. Only when they write fourteen the form can be send.

It did.
For the record, I had a site generating 20 Form Builder spam messages per day. I installed this last week and haven't had even 1 spam message through. Perfect.
