Does Facebook know about the thoughts you typed but didn’t post?
If you’re worried about snooping by the National Security Agency, HERE‘s something else that might give you pause:
We spend a lot of time thinking about what to post on Facebook. Should you argue that political point your high school friend made? Do your friends really want to see yet another photo of your cat (or baby)? Most of us have, at one time or another, started writing something and then, probably wisely, changed our minds.
Unfortunately, the code in your browser that powers Facebook still knows what you typed—even if you decide not to publish it.* It turns out that the things you explicitly choose not to share aren’t entirely private.
Facebook calls these unposted thoughts “self-censorship,” and insights into how it collects these nonposts can be found in a recent paper written by two Facebookers. Sauvik Das, a Ph.D. student at Carnegie Mellon and summer software engineer intern at Facebook, and Adam Kramer, a Facebook data scientist, have put online an article presenting their study of the self-censorship behavior collected from 5 million English-speaking Facebook users. (The paper was also published at the International Conference on Weblogs and Social Media.*) It reveals a lot about how Facebook monitors our unshared thoughts and what it thinks about them.
The study examined aborted status updates, posts on other people’s timelines, and comments on others’ posts. To collect the text you type, Facebook sends code to your browser. That code automatically analyzes what you type into any text box and reports metadata back to Facebook.
Storing text as you type isn’t uncommon on other websites. For example, if you use Gmail, your draft messages are automatically saved as you type them. Even if you close the browser without saving, you can usually find a (nearly) complete copy of the email you were typing in your Drafts folder. Facebook is using essentially the same technology here. The difference is that Google is saving your messages to help you. Facebook users don’t expect their unposted thoughts to be collected, nor do they benefit from it.
