    Can I use a hidden box for spam protection?

    Asked by jerad penick on October 30, 2013 at 03:09 PM

    Can I use a hidden box for spam protection? How would I be to use the hidden box feature in that way in your form builder? I would like the form to be rejected if the hidden box has any information in it (filled by a bot). I always have trouble with CAPTCHA verification and reading them myself.  I do not want to put my potential customers through the same trouble. The simpler the form, the more likely they will fill it out. Thank you.

    Hi Jerad,

    Yes, you can use that technique to deter bots. If I am not mistaken, that's what they called honeypot technique. :)

    Anyway, try the following.

    1. Add a hidden box field to your form.

    2. Create a hide/show condition that would hide the entire form or submit button once the hidden field is filled.

    So when the bots automatically filled all the fields thru source code, it will trigger the hide/show condition and the form cannot be submitted anymore since the submit button is removed.

    Hope this helps. Thanks!
