    How can I block an IP from submission?

    Asked by DrNoMosquito on June 01, 2017 at 03:59 AM


    Someone is using all my submission limits.

    How can I block his/her IP?

    Or even how can I prevent that someone is submitting the form more than 3 times within one month?

    You can block the user submitting the form more than once by following this guide: https://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form

    You can set that each time the IP of the user is checked and, therefore, blocked if the IP is repeated.

    Unfortunately, you can not automatically block someone who submitted the form more than 3 times.

    Hope this helps.

    Let us know if you have any further questions.

    Thank you!
