nice!
Currently it's only really for page likes and FB offers though, so it doesn't really pertain to most of what the CPA affiliates are doing. But good start in the right direction for them.
No you can place pixels on offers and run auto CPM- have some minor success with it, typically FB will overspend beyond the set CPA by far.
