Why is having email addresses on my website a security risk?

Email addresses in plain text can be harvested by spambots that crawl the web, resulting in increased spam, phishing attempts, and potential security breaches targeting those addresses.

How do I protect email addresses on my website?

Use contact forms instead of displaying email addresses, encode email addresses with HTML entities or JavaScript, or use a CAPTCHA-protected mailto link. These methods prevent automated harvesting while keeping the address accessible to real users.
