As social networking gains in popularity so does concerns about privacy. One of the most widely adopted sites, Facebook, offers a lot of customization when it comes to who sees what on a member's profile. Recently, Facebook gave users the option to open up their profiles and allow any section to be visible by everyone on internet. They also added a publisher control so users could modify who is able and not able to see content published on their profiles.
On my Facebook profile, everything was set to either "Friends of Friends" or "Only Friends" except anything that had to do with promoting my blog. The website was visible by everyone who visited my profile as well as any announcements about new blog entries. My default publisher control setting was set to "Only Friends" and I selectively choose when something was supposed to be publicly available. Personal status updates that had nothing to do with my site had a tiny lock icon under the post indicating only friends were allowed to see it.
After I upgraded to the Facebook 3.0 iPhone app, I noticed that status updates via the app did not have the tiny lock under the post. At first, I figured these updates would follow my default publisher control setting and would only be viewable by friends. Eventually, my curiosity got the better of me and I created a dummy account to see what my Facebook profile looked like to non-friends. To my surprise, every update made via the iPhone app was visible on my wall and did not follow my privacy settings. Since there are no privacy controls on the Facebook iPhone app, the most logical thing would be for any update to follow the default publisher control setting unless given the option to choose otherwise.
After my discovery, I felt my only option was to lock down my Facebook profile and make all my status updates visible by only friends until Facebook allows me to have more control over who sees posts made via my iPhone. I conclude with a word of caution for those using the Facebook iPhone app: If your profile privacy is set to "Everyone" yet you want to selectively control which updates are visible on your wall by non-friends, just keep in mind any updates made on the iPhone offer no privacy control and are all public.
UPDATE: 9/8/09 - According to TechCrunch, Facebook has resolved this bug with a server-side fix, although I have not tested it myself. The article also addresses other privacy bugs on the Facebook iPhone app.
