How Can I Stop Receive Forms Dayli?

I'm receiving forms with no submissions or answers every day, how can i stop it?

If the submissions are blank and/or you suspect them as spam, you can set a captcha field in your form. Here's a guide that you can refer to: http://www.jotform.com/help/205-How-to-Add-a-Captcha 

You can also set the limitations on your form by using a unique question or by checking the IP/browser cache: http://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form 

Do let us know if that helps.
