End Of The Like Gate!
When you like a Facebook page, Facebook wants to make sure you really like that page. Facebook announced recently that it will end the process known as the like gate, where users would have to like a page to enter a contest or receive more points in a game.
Facebook detailed this change in a developers blog post:
You must not incentivize people to use social plugins or to like a Page. This includes offering rewards, or gating apps or app content based on whether or not a person has liked a Page. It remains acceptable to incentivize people to login to your app, checkin at a place or enter a promotion on your app’s Page. To ensure quality connections and help businesses reach the people who matter to them, we want people to like Pages because they want to connect and hear from the business, not because of artificial incentives. We believe this update will benefit people and advertisers alike.
