WP Email Invisibliser is a WordPress plugin by adamsargant to hide emails from spambots.
Simply use the shortcode [hide_email [email protected]] to hide [email protected] from harvesters but create a clickable email link.
The plugin removes readable emails from the html outpout, replaces them with a div that uses the hex converted email address in a class and then replaces that div with javascript on the fly to create a clickable link. If the viewers browser is not javascript enabled they will see a short message explaining why they can’t see the email.
