    Setting a unique submissions through IP

    Asked by frostynova on May 18, 2016 at 12:19 PM
    2) I also need to know how I can ban a submitter. Or add some logic where once a submission is done from an IP, no more submissions will be taken in.

    This is possible by using the Unique Submission in the Preferences. Please follow the steps below:

    1. Click the "Preferences" button in the toolbar.

    2. In the Preferences window, go to "Advanced" tab and then choose "Strict Check" as the option for Unique Submission. Strict check controls the IP address.
