Content Filter (Reverse)

I’ve seen at this page ( ) a plugin named “Content Filter” (contentFilter.jar - 1.6.1 - Dec 1, 2009).

It’s a “blacklist” of terms, that censors what’s listed in the system. I’m wondering if I can have a “whitelist” version of this, which is basically the opposite, and censors what is not listed in the system.

I was advised to contact Conor Hayes to create this “alternative” version. Any ideas?
