I never ran anything in Facebook, and I'd like to know if they are ok to build a list?
I mean, I'd use a simple Squeeze Page to build a list in one of these markets:
Dating Advice / PUA (for men);
Weight Loss;
Freelancing Online;
BoddyBuilding;
Then I'd promote affiliate offers to these people.
What are my chances of being banned using those verticals?
Dating is frowned upon (more like attacked) by Facebook.
Bodybuilding has the problem with claims, same with weight loss.
It's possible for sure, but I would explore other verticals.
