Facebook knows you a lot, I mean a lot. When updating statuses, adding friends, sending messages, tagging photos etc, Facebook does actually recording every move that you makes. It's might be a mundane issue to you, but the fact is someone is monitoring you. Still reading this?
There's a story behind this. Max Schrems, a 24 year-old law student from Vienna, Austria actually sent a request to get a copy of his personal information that had been collected by Facebook. After waiting for some time, Facebook did sent him a disc. Inside the disc are 1,222 PDF files, detailing each and every moves that he made which includes deleted messages, relationships, geotagged photos, and everything that had been posted.
So how much data is Facebook collecting on you?
