Dear ANONYMOUS
I think that you should not get involved in that fake Facebook account because you could get in serious trouble and really hurt someones feelings.
Some ways that you could try to do to Stop your friends from doing one is to tell them if that person that they were going to pick on was them how would they feel.
You could also tell a trusted adult that you wouldn't mind telling him/her the problem.
If both ways don't make a different and you notice that that person getting picked on is kind of depressed you could become his/her friend you could also get a couple of your own friends and tell them about the problem and so they become his/her friends too and when the bully sees all those people around him/her they will probably stop.
If they don't then i think that you should call the police and tell them about the problem and let them handle it.
At least you would of done the right thing and not be a bystander :)
