I am looking for a plugin that will stop a comment from being entered if it includes a term and will tell the commenter that the comment cannot be posted because it contains X (whatever was blocked). I do not want to mark the comment as spam or to put it into moderation and I do not want the term to be changed to something else. I want them to know what the issue is so they can adjust their comment and try again.
Ideally, it would function exactly like the Censor Block hack for phpBB, but I could get away with functionality similar to the CommentCensor plugin for Nucleus CMS. Does anyone know if such a hack exists?
I appreciate any replies. Thanks! :)
