A badly worded update, liking the wrong thing, blocking the wrong person – there’s a lot of things that can go wrong on Facebook. The problem is the same as the problem with the whole internet: everyone can see what you’re doing. These fools didn’t realize it, though, and it cost them big time. They lost their jobs, money, freedom, and a whole lotta respect just because they forgot that social media wasn’t their personal diary. Before you make the same mistake, make sure you hear the cautionary tales of this unhappy bunch.
