    To prevent spammers to keep filling your form out and submitting it, you can limit the form by IP address or Cookies

    Please follow these steps

    On the Form Builder:

    1. Open "Setup & Embed" tab on toolbar,

    2. Click on "Preferences"

    3. Go to "Form Limits"

    4. Select the Unique Submission option you prefer. (Strict Check or Loose Check)


    Loose check controls the cookie.

    Strict check also controls the IP address.

    5. Close and Save your Form.


    If you select Strict Check, people in the same network (in the same school, college,university, institution ) will not be able to make submissions, as the IP address for the network would be the same.

    If you are considering the target audience as students in the same school, Loose Check should be chosen.
