Social networking site users have to worry about more than just potential employers digging up their dirt online now.
One of the most prestigious U.K. universities has begun to scan the social networking sites seeking snapshots and other evidence of misbehavior that qualifies for formal disciplinary action. Students at Oxford University are outraged that school leaders are scanning Facebook and disciplining students based on what they find there.

Outrage isn't going to stop it. People need to realize the minute you are posting information, pictures and videos of yourself doing things online it is very hard to remove them or prevent them from being seen. The internet is NOT a very private place, treating it as one is a huge mistake. Think before you post.
