Facebook Like Gating is no longer allowed according to a change in Facebook Platform policy effective November 5, 2014. This means you can no longer incentivize people to like your Page before seeing an app’s content.
Customers who have built Facebook apps using our App Builder and have applied Like Gates to those apps are affected by this Facebook Platform policy change. We will deprecate Like Gate functionality from our App Builder tool on November 18, 2014.
