There's no getting around the fact that most of us spend a lot of time online. We learn online, we catch up with friends online, we check out stuff we're interested in, and we express ourselves - letting other people know who we are. Unfortunately, we can't always know that the people we are engaging with are who they say they are, that the information we're reading is true and accurate, or that the people seeing our posts are there for the right reasons. As such, it is really important that you know how to protect yourself, check to see if what you're seeing is true and real, and where to go if things go wrong.
