Inappropriate vs appropriate

I too have seen students create a fake Facebook account to make fun of a group of students, post digital inappropriate pictures on snapchat or Facebook, get into an argument on twitter, or share pictures and hide them behind a fake icon on their phone etc etc etc....  People find confidence in sitting behind a screen posting and commenting inappropriately.  It is much more difficult to do that in person.    A few things I do as a teacher:  I don't accept students as friends on Facebook.  I rarely post, and if I do, it is positive.  I try to be a good example.   I try to always teach students to live by the golden rule.
