? I think you misunderstand what it does.
You can have a Fake or the correct file - nothing else.

Instead of having to put hit and runners, Known as a leecher, in a miserable group or ban from attachments, or better is to Inform them, it would be wise to contribute, it is really a good Idea. And you can always deny why they have a bad attachment LOL. In fact you wouldn't need to prune for inactivity. Oh such evil thoughts LOL :D

If it did that, would it still be considered a fake file?

Why not just deny them access to the file instead?
