    You can actually do this by changing your form submissions to Unique Submissions then set it to " Strict Check ". This will prevent an IP from sending more then one submission. Also, something else that will help with that is Limiting the Submissions as well. Additionally you may find it useful to apply a Captcha Field to your form which can help too.

    If you continue having spamming issues on your form please let us know so that we can help you to further prevent this problem.
