Blacklist Check for form submission

[cheyennemtnman]

I have created many forms over the years and invariably there are form bots that access forms and create false entries promoting porn, other sites, etc. Is there a way when a fabrik form is submitted the email address entered can be checked for blacklisted domains and the record would not be created if it matches a domain on the blacklist?

You can add a captcha element or a php validation on the email field or a php plugin for checking/aborting before submission.

Awesome way of expression. Look after it up!

There's an option on the email validation to check that it's a valid MX domain, but I don't currently have RBL support. I'll take a look see if there's any handy dandy Composer modules for doing RBL lookups.

Although as Troester says, the CAPTCHA element using the Google nocaptcha method is your best defense, which can even be set to invisible if you want.
