Facebook launches Graph API 1.0, which allows user data collection.
Facebook opened its doors to third-party apps. The apps could demand for a substantial amount of data, including the info of users and their friends, without stating a reason for wanting the data. In addition, the apps could retrieve the data from a user’s public profile (including their name, location, gender), as well as their friends’ names, political views, religion, education, and more. If the developers extended their permission, they could even gain access to a user’s private messages. -
Facebook adjusts its design to make it less obvious to users that they were retrieving your private information.
In the beginning, when playing games on Facebook, you were offered you two options: to “Allow” or “Don’t Allow” your personal data to be accessed, and posted on your behalf. As time passed, the design was changed for there to only be one button which showed the option to “Play Game” in big letters. In small letters, the fact that the app would access your basic info, email address, birthday, location, was shown. There was no option to not allow this, the only option was to play the game. -
