Spam Protect
 
The 'spam protect' feature prevents the possibility of a form filler to spam your form and shower you with entries. Once a form filler presses on the 'submit' button he/she is prompted to fill in a number.

All you need to do in order to activate this feature is:
1) enter your form in the form creator
2) check the "Spam Protect" checkbox situated in the 'Settings'.
