Facebook is free on the app store for anyone to use.
Facebook is a worldwide app that people use around the global world.
I think students should not have a Facebook account until they are 16 or over. Someone can say that they are 10 and they are really 40, and they can hunt you down and do very mean things to you. People can also say really mean language on Facebook.
On the other hand Facebook has some advantages.
Facebook is not good for people 15 or under because people can send mean things and you could copy off him or here, and then not just they will get reported but you will too. You will learn a lesson if you copy mean things from other people then get reported. That is why I think that Facebook is bad for kids 15 or under.
