I was writing my personal website and thought about creation of contact form. Not a big deal....
But I would like to protect me somehow from auto generated requests by malicious scripts.
Captcha is not an option because it would discourage potential senders to contact me.
I tried to look how others handled this problem.
Among many unprotected forms I found pretty interesting example:
I can't explain the purpose of hidden input fields and I guess they have something to do with filtering malicious users from good users.
But. Am I right? How are they used?
Website where I picked this form website
