Paul Fenwick graced us with the following presentation at Barcamp Melbourne. Armed with only the documentation from Facebook’s API he proceded to submit queries to their query engine and it is amazing what he dug up on the volunteers who agreed to let him “hack” their accounts.
Bottom line: Facebook apps are scary because they open your info veins via the back door of applications shared with your “friends.” I don’t know about you but I have quite a few non savvy friends who are nowhere as paranoid as I am. I like using Facebook to keep up to date with my friends, but I don’t want people dredging up stuff on me via my friends’ lack of savvy. So your only hope is to disable *ALL* facebook apps.
