    There are two known ways on how to prevent your forms from being spammed. First is by using a captcha field in your form to deter bots from automatically submitting your form, and to make it harder for a human spammer to do his job.


    The other method is by configuring your form to accept only unique submissions, that is, one submission per person or IP address.

    To learn more about that, click the link below:

    Unique Submission in Forms

    To find out the IP Addresses of people who submitted your form, go to My Forms, click on the specific form then click the submissions button.

    In your submissions page, click the settings icon then check the IP option to have it displayed.


    If you have other queries or concerns, please let us know. Thank you!
