You're thinking about it the wrong way.
You'd post a regular comment and then use the HIDE tag to say "The OP is full crap." So there wouldn't be any empty post, just a normal post with extra content for those in the same group. As a bonus, post counts aren't an issue doing it that way.
The biggest problem I have with that MOD is that it uses group numbers for the advanced features, but it takes a litttle work for users to see their group number(s) -- and there may not be a way to find group numbers for groups that you're not a member of.
Anyway, that's getting off of the topic at hand; I just wanted to try to suggest something for your situation. If you want something else, you might want to consider a MOD request.
