Funny thing, I’ve created PDF’s and none of them have layers.

Depends on the file format, what software created it, and what software you are using to open it up.

I don't need to know the specific details to know this sort of thing happens. You should have seen what was going on with transmitted files back before they had standards.

But have you created a fraudulent PDF? =)
