How are you protecting your Marketo Forms from being spammed?

[Chris_Saporito]

@SanfordWhiteman now that we can add CAPTCHA constraints to triggers & filters for form submissions, are there any additional benefits to the setup you covered on the webinar? We're getting hit with a high volume of spam submissions to one particular form. I tried the honeypot method as well but that's not catching any of these spam submissions. CAPTCHA seems to be fairly accurate, although when filtering raw scores <0.6 I'm still seeing a few valid submissions.

Nope, no need for that approach now that reCAPTCHA is built into Marketo.

Honeypots don’t do anything against spammers with any skill, so we never use ‘em.

There are always some false negatives with reCAPTCHA because some people interact with forms in a less “human” way even though they’re human.
