    Hi Frederico,

    We apologize for any inconvenience this may have caused. Unfortunately, validating fake emails or unregistered emails is not possible for Jotform. If you want to prevent users to make submissions on the same form, please take look at this page in our User Guide. This can be useful.

    If you have any other concerns, feel free to contact us. Our team will be happy to assist you. Thanks for using JotForm.
