<p>Many spammers bypass the comment form and send requests to the WordPress backend directly. This plugin creates a “nonce” field for your comment form, similar to the ones used in the administration backend.</p>
<h3>Troubleshooting</h3>
<p>RSCV not working? Use the following steps to try and solve the problem.</p>
<ol>
<li>Make sure <code><?php do_action('comment_form'); ?></code> is in your template’s comments.php, inside the <code><form></code> tags.</li>
<li>Still not working? Ask on the forums.</li>
</ol>
