Is it normal to make fake facebook accounts?

Me and all of my friends like to make fake facebook accounts and to troll people. We made a lot of people very upset over this and photoshopped ourselves into their pictures. We also had very in-depth conversations with them and found out a lot of things that we did not want to know. (i.e. somebody would have sex with a horse so that he could have sex with us). We had a lot of fun doing this, but is it normal???
