    3 Plugin Name: emObA - Email Obfuscator Advanced
    4 Description: Scans pages, posts, comments for email addresses and creates mailto links which are difficult for 'bot harvesters to find. Typing [email protected] results in a "A-B-C" link;  href="mailto:" links are preserved but obfuscated; the special occurrence "[Name] [email protected]"  is recognized and results in a link on "Name".  Without JavaScript, hovering  pops up the email with graphic glyphs for "@" and ".".  (Based on eMob Email Obfuscator 1.1 by Billy Halsey.)

    13 This plugin effectively and automatically makes it very difficult for spambots to harvest email addresses from your WordPress-powered blog. Email addresses may be placed in posts, comments, and pages, plain, as html links, or in a special "easy email" form, and they are automatically protected by emObA. All email addresses appearing on your blog will appear on the screen as active links to normal, valid, and correct email addresses (the actual email is seen in the status bar when hovering), but to spambots they will have no recognizable features.

     24These will appear as standard email links displaying "Name". A bare email will appear as a link `you ^ example com` (punctuated with text in place of @ and .), since there is no Name.
    2525 
    2626This is accomplished with a combination of WordPress filter hooks and JavaScript. If the browser is JavaScript-enabled, visitors to the site will see active email address links. If JavaScript is not enabled, hovering over the "link" will bring up a popup showing the email in human-readable form, eg `you [@] example [.] com`.  The [@] and [.] are  graphic images, not text, so the parts of the address are separated by lengthy runs of html (`<img ... />`).
