<p>Is this the ultimate in automated ‘bot Spam Killers?</p>
<p>Spam is the bane of WordPress admin’s lives; auto-generated Spam can bypass unset hidden fields from the WordPress comment page by directly submitting the comment to WordPress.</p>
<p>This plugin does two things:</p>
<ul>
<li>Removes the ‘Comment Author URL’ field from the WordPress comments form; for most non-technical blogs this optional field is irrelevant.</li>
<li>Kills WP (hey that saves some CPU cycles) if a comment is submitted which contains a Comment Author URL.</li>
</ul>
<p>Website spam ‘bots have two aims, firstly they populate spam links within the main body of a spam comment, and the spam ‘bot also includes the spam destination in the Comment Author URL of the comment field.</p>
<p>We put together this little plugin as despite running two other anti-spam plugins + Google Captcha, ‘bot spam was still getting through. This was resulting in an hour or so each week weeding out the real comments that had fallen into the spam bucket due to the real commenter failing to complete the Google Captcha correctly. We also noticed that real user comments reduced with Google Captcha in place.</p>
<p>We don’t need to stand for this any longer; say goodbye to Comment Author URL Spam and save CPU cycles!</p>

<p>Few users are familiar with the comment block list built into WordPress. Located in the WordPress admin area under “Settings”—“Discussion”, that block list for incoming comments accepts values (words) to identify spam by.</p>
<p>Additionally to plugins like <a href="https://wordpress.org/plugins/antispam-bee/" rel="ugc">Antispam Bee</a> in order to fight spam successfully a curated comment block list is recommendable. You can either update the list manually, or utilize a very detailed global <a href="https://github.com/splorp/wordpress-comment-blacklist" rel="nofollow ugc">comment block list</a> that gets updated on a regular basis.</p>
<p>Block List Updater has been developed to keep your comment block list in your WordPress installation up to speed with the curated global list on GitHub.</p>
<p>The plugin will check the global comment block list on GitHub multiple times a day. Whenever new anti-spam values have been added to the global list, Block List Updater will read the global list and update your WordPress database accordingly. While the check-up process will run several times a day, the plugin will only update the database when it detects an actual change of the global comment block list on GitHub.</p>
