Check for exposed email addresses
Email addresses shown in plain text on a webpage are harvested by spammers, and checking for them protects against spam. This tool checks whether email addresses are visible in plain text on a page, so you can find and protect exposed addresses.
Why exposed addresses attract spam
Spammers run automated harvesters that scan web pages for anything looking like an email address, and any address in plain text in the page source is easily collected and added to spam lists. Once harvested, an address receives a steady stream of spam that is hard to stop. Checking a page for plain-text addresses reveals what is exposed, so you can protect them, by obfuscating, using a contact form, or an image, before the harvesters find them. This is a simple, worthwhile check for any site that publishes contact addresses.
