I think that some kids don't believe that it's wrong or it's even funny. The kids keep bullyong each other because they find it amusing or they are just mean. I don't think that the community can stop them beacause they can still do it, but the adults won't know about, unless the victim tells somone about, but they might be to scared of what the bully will do so they might not tell anyone.
