Spam Form Fills

Hi all, Was hoping someone could help me with an issue we have been experiencing recently.

We've been getting a ton of submissions to our demo request page with complete junk information. All fields are filled out, but the person and company do not exist and the rest is gibberish.

I know Marketo does things like the hidden fields on forms to segment out bots, but I'm not sure how to filter out human spammers that are filling out the form manually?

Any help would be greatly appreciated!

Hi Ashley,

I'm just curious, how do you know these are human spammers?  This really sounds like bot behavior to me.

Not 100% sure if they are human or bots.. But since the Marketo filter is not picking them up, I just assumed they were actual form fills. Could be wrong though!

Have you put in a hidden field as a honeypot for bot form fills?

How do you do the "honey pot"? I'm having the same issue - it's so bad that I've had to unpublish all PPC landing pages. My dev team is concerned about security, and my sales team is questioning the quality of my inbound efforts.

Hey Christine, just add a field that should remain NULL, but if it gets a value then that means that a bot filled in the form. If it's a person, they can't see the field so they won't fill it in

You can add the familiar Google reCAPTCHA protection to Marketo forms: MktoForms2 :: reCAPTCHA

You pair it with Marketo webhook to verify submissions, and it is effectively un-bottable.

I am not sure how to use webhook with the sample you posted.

Thought you said on the other thread that the back end was already set up by another dev.

Hi Sanford Whiteman thanks for the sharing! Can you clarify for me where I should put the js in your link? Do we add to the header of each page that has a form? I've got a very basic understanding of js and css.

Any reason we'd want to use this code you've posted before instead of the one linked above?
