Painlessly purge spammy comments from your WordPress database to save space.
This plugin has been tested on multiple WordPress installations with various numbers of comments. However, there is still a possibility that one or more other plugins will interfere with the way it operates. I would strongly suggest backing up your database before using the plugin just to be safe.
To prevent your subscribers from having direct access to your database, the only users that can actually see the link are those who have the authority to moderate comments. I am working under the assumption that, if you trust someone to delete/publish/spam comments, you can trust them to delete spam comments as well. In the future, I might add a separate capability class.
The plugin itself will work, but you won't have the same kind of access due to changes in the administration menu. To correct this, expect a new version of the plugin to be released in November (2008) that will check WordPress versions and change access accordingly.
