Posting an email address inside your blog post increases the risk of directing spams towards email inbox. BetterAntiSpamBot is a free WordPress plugin that lets you post email address with better protection against spambots. The plugin encrypts email addresses with a dynamically generated JavaScript function.
How It Works ?
When encrypted email addresses are present inside your contnet like post or page, BetterAntiSpamBot automatically adds a single, uniquely generated JavaScript function to footer.
First, the plugin generates a key and splits it into variables. Then it randomly generates variable-, function- and parameter names using similar UTF-8 characters. Finally the code gets compressed and reduced to one line. And in this way it makes automated email harvesting pretty hard for spammers.
Installation & Usage:
Simply click “@” button present in your visual editor’s toolbar.
OR just type the shortcode changing email address to yours:
- Posts: Shortcode
[bspam mail="your@mail.tld"]Display Text[/bspam] - Posts: Shortcode extension
[bspam mail="your@mail.tld" alias="youralias"]Display Text[/bspam]
The plugin is also integrated in PHP:
- PHP:
global $betterantispambot; echo '<a href="'.$betterantispambot->setmail("your@mail.tld").'>Display Text</a>'; - PHP:
global $betterantispambot; echo '<a href="'.$betterantispambot->setmail("your@mail.tld", "youralias").'>Display Text</a>';
All above codes will output a clickable link “Display Text”:
<a href="javascript:decrypt(0)">Display Text</a><a href="javascript:decrypt('youralias')">Display Text</a><a href="javascript:decrypt(0)">Display Text</a><a href="javascript:decrypt('youralias')">Display Text</a>
Security Levels:
Other than this you can also change the plugin’s security levels to Best, Good, Minimal, Realnames (Debug) and also its Variable length from its options page (Dashboard -> Settings -> BSPAM).
