Implements strong, automatic anti-spam protection for email addresses that appear in the text of articles.
The "wp-spamspan" plugin implements strong, automatic anti-spam protection for email addresses in content on a WordPress site. To spam crawling 'bots, email addresses appear in obfuscated form. To human visitors, they appear as clickable links.
There are two parts to the wp-spamspan process. First, the message text is scanned for email addresses and they are rewritten into an obfuscated form.
So, if you have a post that contains the text:
This plugin will rewrite that address to display as:
chip [at] example [dot] com
A 'bot that harvests email addresses will see this text and won't be able to extract a usable email address from it.
This plugin incorporates spamspan.js, which is licensed and published separately (but bundled into this plugin distribution). The home page for spamspan.js is: http://www.spamspan.com/
