Privacy Notes Spambot Buster not only defeats robots harvesting email addresses on web pages, it also completely nullifies their harvesting efforts when they scan

  • newsletters,

  • newsgroup postings,

  • discussion list postings,

  • instant messages,

  • print ads,

  • and any other document,

where the Privacy Notes Spambot Buster method is used in lieu of publishing an email address.

When no email address is present, it can't be harvested.

Instead of me just talking about it, let me show you. The following link contains no email address, not encoded, not encrypted, not generated by JavaScript. It's not on the web page. But if you click the link, your browser will cause your email program to open with a new email and with the correct email address pre-filled in — just as if the link was a mailto: link.

A note about email address cloaking on web pages —

Email address cloaking methods abound. The methods include encoding with special characters, encryption, generating with JavaScript, and others, some very ingenious.

But they all have a weakness in common — the browser has to decode/decrypt/generate the email address into it's original form before it can be used.

It is a weakness because browsers and email harvesting robots are both software and, no matter the cloaking method, if a browser can extract the email address then robots can be programmed to extract it, too.

With the Privacy Notes Spambot Buster method, cloaking isn't necessary because there is no email address to cloak.

When no email address is present, it can't be harvested.

(A special "thank you" to Bob McElwain of for suggesting the name "Spambot Buster")
