Among other things the reason I quit facebook is because of people who have no problem trading my information for their gain. I got tired of blocking requests from an aunt addicted to farmville, for instance. She's exactly who I had in mind when I said people will subvert controls I put in place for their own benefit. She'd happily click a button that downloaded all my data shared to her with Facebook if it meant an extra in game reward. But do I want to block her from all my updates? Not really. However given the choice of doing that and sharing my data I quite facebook. I realize not everyone is the same.
