Facebook app privacy: It's complicated
Earlier this week I wrote a post about how I didn't like that I couldn't alter the Facebook Connect privacy settings for updates from Foursquare, an iPhone app that shares my location through a GPS-enabled city directory. It didn't make sense to me that Facebook Connect information was automatically visible to anyone who had access to posts on my "wall," whereas privacy settings on a third-party app embedded directly on my profile were much more fine-tuned, allowing me to restrict them to specific subsets of friends.
Not quite. I've been e-mailing back and forth with Facebook, and I've gotten some clarification on how the process exactly works. Privacy controls for embedded apps aren't as simple as I'd thought. I can opt to block the "box" for a third-party game like Mafia Wars or Farmville, as the privacy controls indicate, but activity from those apps--i.e. if I just picked up a new weapon in Mafia Wars--will still show up to anyone who can see what I post on my Facebook wall, like status messages and new friend connections. (You can, however, block individual Platform apps from posting to your wall in the first place.)
