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.

This plugin automatically scatters invisible links to <a href="http://www.projecthoneypot.org/" rel="nofollow ugc">Project Honey Pot</a> spam traps 
throughout your wordpress blog to help catch and stop spammers.
Project Honey Pot is the first and only distributed system for identifying spammers and the spambots they use 
to scrape addresses from your website. Using the Project Honey Pot system you can install addresses that are 
custom-tagged to the time and IP address of a visitor to your site. If one of these addresses begins receiving 
email Project Honey Pot not only can tell that the messages are spam, but also the exact moment when the address 
was harvested and the IP address that gathered it.
Install this plugin to help contribute to the project and catch spammers by hiding links to honey pots (spam traps) 
in your blog. The links are never visible to human visitors, but the spambots and crawlers follow them straight into 
the traps.
Note: this plugin will not directly prevent spam on your site, but will help prevent spam for everyone by helping to catch the spammers.
If you also want to use the Project Honey Pot API to detect and block spammers from your site, try the <a href="https://wordpress.org/extend/plugins/httpbl/" rel="ugc">http:BL plugin</a>.
