“Compare People” Facebook App Selling User Info
I’m not surprised. Something about the app struck me as quite sleazy from the beginning, but I avoided it too efficiently to notice any premium options. Maybe the features discussed here were pulled later, but I can’t seem to recall hearing about this matter before.
The same author has a later post with more details (read: screenshots) on what the premium mode that exposes the actions of your friends looks (or looked?) like.
