Yesterday, Facebook tweaked its Platform Policies, and while some of the changes are subtle, there's one which is very welcome: from now, the concept of offering access to apps or content in return for Likes is banned.
Straight outta the mouth of Zuckerberg & Co., the new rule reads like this:
You must not incentivise 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 incentivise 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.
