i've been advertising on facebook's news feed for desktop recently and used their optimized CPM function. My first campaign was fine with CPMs of $8-12, but from my 2nd campaign onwards, my CPM rates would start at $20+ and above and stick about there. I have friends who target the same interests with CPMs of $8-12 but mine is just permanently at $20+ or higher.
Is my account being "blacklisted" or "slapped" in some way?
