JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
To prevent spam, you can add a captcha field to your forms - this will require manual validation by a real person, and prevent automated bots from submitting your form.
Alternatively, you can also try adding form submission limits, to prevent multiple submissions from the same IP address, or to prevent multiple entries that have a certain field filled in the same way (a Unique Question).
Please let us know if you need further assistance.
