With this new feature, a hidden form field stops spambots from filling and submitting your contact form without using third-party services.
This will not stop human spammers and sophisticated spam bots.
Context
To stop spammers, many sites use Google reCAPTCHA and other similar services. These services use a private key that requires a backend(server or serverless function). This solution is for static websites that don't have a backend solution.
This is an enhancement or feature.
