5 Description: Akismet checks your comments against the Akismet web service to see if they look like spam or not. You need a <a href="http://wordpress.com/api-keys/">WordPress.com API key</a> to use it. You can review the spam it catches under "Comments." To show off your Akismet stats just put <code><?php akismet_counter(); ?></code> in your template. See also: <a href="http://wordpress.org/extend/plugins/stats/">WP Stats plugin</a>.
