<p>Comment Blacklist Manager retrieves a list of terms from a remote source and updates the <code>disallowed_keys</code> setting in WordPress. The plugin will automatically fetch a list of terms on a regular schedule and update the contents of the “Disallowed Comment Keys” field. Terms added manually via the “Local Blacklist” field will be retained during the scheduled updates. Terms added manually to the “Excluded Terms” field will be removed from the list.</p>
<p>The default list of terms is fetched from a <a href="https://github.com/splorp/wordpress-comment-blacklist/" title="Comment Blacklist for WordPress" rel="nofollow ugc">GitHub</a> repository maintained by <a href="https://splorp.com/" title="Interface considerations. Gadget accumulation. Typography. Scotch." rel="nofollow ugc">Grant Hutchinson</a>.</p>

Does as advertised. I especially liked how you can exclude words from the automated blacklist if they don't suit your website.
