<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>


Comment Blacklist Manager

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



Great Little Plugin

Remotely add terms to the WordPress Disallowed Comment Keys field to manage spam.

<p>The Email Blacklist Add-on for Gravity Forms was built to help block submissions from users with generic or competitors email addresses. Prevent the user from processing the form and stop non-qualified leads from being collected.</p>
<p>This plugin allows site admins to create a list of domains that if used in an email field on a Gravity Form it will cause a validation error and block the submission. A default email blacklist and validation message can be created to use across all email fields. These default settings can be overridden on a per email field basis.</p>
<p>Global settings can be added on ‘Forms’ > ‘Settings’ > ‘Email Blacklist’. To add settings to an individual email field, select the field and navigate to the ‘Advanced Settings’ tab.</p>
<p>This plugin works by blocking either individual email addresses (ex. jsmith@gmail.com), email address domains (ex. gmail.com), and/or email address top-level domains (ex. *.com).</p>

<h3>Instructions</h3>
<h3>Global Blacklist Settings</h3>
<p>Once set up, these settings will be used on all email input fields across all the Gravity Forms used on the site. They can be overridden by the individual email blacklist settings below.</p>
<ol>
<li>Once Logged into your site navigate to ‘Forms’ > ‘Settings’ > ‘Email Blacklist’</li>
<li>In the ‘Global Blacklisted Emails’ input enter a comma separated list of blacklisted domains (ie. hotmail.com), email addresses (ie. user@aol.com), and/or include the wildcard notation to block top-level domains (ie. *.com). This setting can be overridden on individual email fields in the advanced settings.</li>
<li>In the ‘Global Validation Message’ input enter a default error message if a blacklisted email is submitted. This setting can be overridden on individual email fields in the advanced settings.</li>
<li>Select the ‘Global Invalid Entry Procedure’ to determine how the blacklisted submissions should be handled, with validation error or collected and marked as spam.</li>
<li>Click the ‘Update Settings’ button to save the settings.</li>
</ol>
<h3>Individual Email Input Blacklist Settings</h3>
<p>Once set up these settings will be used on this form only and in place of the global blacklist settings above.</p>
<ol>
<li>Once Logged into your site navigate to the Gravity Form you would like to update.</li>
<li>Add or update an existing email input field on the form.</li>
<li>Go to the ‘Advanced Settings’ tab for the ‘Blacklisted Emails’ input.</li>
<li>In the ‘Blacklisted Emails’ input enter a comma separated list of blacklisted domains (ie. hotmail.com), email addresses (ie. user@aol.com), and/or include the wildcard notation to block top-level domains (ie. *.com). This will override the globally defined blacklisted emails setting. Enter ‘none’ to bypass the global setting and allow all email addresses.</li>
<li>In the ‘Blacklisted Emails Validation Message’ input enter an error message if a blacklisted email is submitted. This will override the globally defined error message.</li>
<li>Select the ‘Invalid Entry Procedure’ to determine how the blacklisted submissions should be handled, with validation error or collected and marked as spam.</li>
<li>Click the ‘Save Form’ button to save the settings.</li>
</ol>
