Some commentors try to abuse the WordPress Comment’s built in URL feature by submitting advertising, spam, or otherwise unwanted links.
Avoid Linkback Abuse tries to prevent this by providing two different modes of operation:
<ul>
<li>Strip all anchors from comment author’s names as they appear 
 in the comments list at the end of posts (always on when 
 the plugin is activated).
<ul>
<li>In addition to the above, this mode will remove 
entirely the ability for commentors to leave a URL. 
Assuming you’re using the default WP Comments plugin 
without any additional comment-modifying plugins, this 
mode still allows commentors to leave their name and email.</li>
</ul>
</li>
</ul>

Avoid Linkback Abuse (ALA)

Remove the URL field from the comments form to prevent linkback spam.
