How does a honeypot stop spam?
The field is hidden from people but visible to bots, which fill in every input they find. Any submission with a value in the hidden field is discarded.
Is a honeypot enough on its own?
It stops most automated spam with zero friction for real visitors. Combine it with rate limits and spam review for forms that attract targeted spam.
Is anything I enter saved or sent to Form Koi?
