This has been going on for a while now. People don't realize that what they do and say on the Internet is not anonymous, especially when you're doing it on a Facebook account with your name and pics on it. This is one reason why once Myspace went downhill, I deleted my account and never made the jump to Facebook. I just didn't see the point, plus I knew that anything posted by me or my friends was visible to my employers both present and future.
Same goes for YouTube videos and twitter accounts. I don't say anything offensive on Twitter so I'm not worried. In fact, I don't say much of anything, more of just following people really.
