Comment Blacklist Manager retrieves a list of terms from a remote source and updates the blacklist_keys setting in WordPress. The plugin will automatically fetch a list of terms on a regular schedule and update the contents of the “Comment Blacklist” 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.
The default list of terms is fetched from a GitHub repository maintained by Grant Hutchinson.
