    How do I block a specific IP address from spamming my form?

    Asked by Disgraceland on May 01, 2014 at 09:18 AM

    I run a facebook page and I use JotForm to collect responses for my page and post it to my page via Zapier. I have certain individuals who spam my responses with crap and it gets posted onto my facebook page.

    Even if I put in the anti spam check, they still bypass it because they are not robots. I need to block their IP addresses from accessing my JotForm. How do I do that?

    Unfortunately, it's not possible to blacklist/block a specific ip address in JotForm. But you might like to use Unique Submission to prevent users to make submissions on the same form. Please visit the url below for more information.
