emObA – Email Obfuscator Advanced plugin effectively and automatically makes it difficult for spambots to harvest email addresses from your WordPress powered blog. Email addresses may be placed in posts, comments, and pages, as html links, in a special “easy email” form, or as the address itself, and they will be protected by emObA automatically. All email addresses appearing on your blog will appear on the screen (if JavaScript is enabled) as active links to normal, valid, and correct email addresses, but to spambots they will have no recognizable features. (As usual, the actual email appears in the status bar when hovering.)
