I have mixed feelings about suggesting this to clients as at the end of the day Facebook has the final word, and you don’t want to be the one with egg on your face.
I would suggest testing this yourself and see how you go with pushing the promoted post boundaries. It makes sense that Facebook would chill on these rules as promoted posts is a huge revenue stream for the company.
Let me know if you have success or not? I would like to see if Facebook are more stringent on brands that have bigger followings as it would affect more of their users.
