One of my clients seems to be plagued by a lot of bot form fills over the past several months. We are looking for recommended solutions. Any Captcha type solutions (or other solutions) that work well with Marketo forms?

Hey @SanfordWhiteman - What if it turns out the invalid form fills are coming from malicious humans? Note that we have global form validation rules in place - one to block consumer email domains and the other to block competitive domains. We could obviously add "malicious" fake domains to to one of the validation rules but I don't think we're seeing much in the way of repeats. I can't think of how this could be solved but perhaps that's due to the limits of my imagination! 🙂
If the email addresses are legit (can receive emails) and don't have other identifying marks (like being from known disposable email domains) then you're kinda out of options. Malicious people submitting at a slow rate from a variety of IP addresses might as well be good leads.
