Few months ago, Facebook shuts down some apps of certain 3rd party Facebook App Developers that collect and sell Facebook user personal information. This issue sparked many outrages among users and everyone is very concern how their private information on Facebook will be shared to somebody else. Technically It is against Facebook’s policy for such thing to happen. But recently, Facebook announced that they allow Facebook apps to collect user private information, with the user’s permission. Basically it means that, the 3rd party app developer can have private information because user allow them to take it.
