An interview with an anonymous Facebook employee on blogsite The Rumpus confirms that yes, Facebook knows exactly who you are stalking and when where you’re clicking and yes it does store all that information. Permanently. It’s a good read but sobering to know for definite just how much Facebooks knows and stores.
The full interview is here, and not all the information is new but a few jump-out statements included:
1. Facebook saves stuff that has been deleted or untagged: that drunken status you deleted when you woke up is still on a server somewhere.
2. Facebook saves your viewing history, it has a log of clicks and so it knows whose pictures you’ve been going through
3. Facebook logs stats like how often you interact with or click on the profile of a given person and makes judgements about how good friends you are with them (you can see this when you start to type a friend’s name into the search box – the results are no longer ordered alphabetically, but by the people you have interacted with the most).
4. Facebook employees can find out any message you’ve sent or detail of your browsing history – ever – simply by querying the server where all this information is stored.
5. Instead of simply relying on trial and error to test out new features, Facebook now do psychological tests on new features, including tracking people’s eyes as they scan the screen.
Enough already, I think you get the gist.
