Money Page Questions - pop unders, back offer scripts

For those of you who run blackhat on FB, do you run back offer scripts (the user clicks back and instead of going back to fb they are sent to another offer), or do you have mobile click pop unders on your landers? Since the money-page is cloaked does it matter if these things are on there? I haven't tried it yet but wondering if anyone has done this and if it has a negative on effect on the account getting flagged.
