Email Link Obfuscation with JavaScript
Many spammers use bots which crawl the net looking for email addresses contained within web pages to add to their spam lists. Over time methods have been created to protect from this. One example includes simply URL Encoding all the characters of an email address in the mailto link and for the link text, or simply adding “nospam” into a portion of their email address. Now that is not enough as the bots have simply been modified to detect email addresses in those formats.
This tool uses JavaScript code to implant the email address into the link after the page is loaded so there are no plain text email addresses in the page when bots crawl. As most of their programs do not parse JavaScript code the email will not be visible to them. The JavaScript code contains an obfuscated set of strings which hides your email address.
Tested and working in Firefox 1+, Opera 8+, Internet Explorer 6+, Safari 3+.
