I've noticed the same discrepancies between charged and reported clicks.
On the top of that i also do have non geographic targeted users (for example peoples from Norway when your demographic is focused United States).
It's good to know that apparently they're doing something i just hope that it's true and that we'll see results of these investigations pretty soon.
But when you see FB policies about artificial minimum CPC i do personally consider that they are on the same side as the MF doing click fraud.
