This site has one purpose: to teach you how to incorporate some spam-filtering into a PHP contact form to reduce the success rate of robotic spam submissions without having to use CAPTCHA images, pictures of cats, or other human-authentication methods that annoy users. It's not designed to be a comprehensive spam solution nor to scan for viruses, ransomware, or scams. It's designed to reduce the amount of spam (especially robotic spam) accepted through the contact form, and nothing more.
