To be honest I don't even know what I think schools should do about it. Schools are institutional, and institutions can lead to bullying, attention-seeking - all sorts of bizarre behaviour, especially when students are all kept within strict age groups. Schools have to protect children from being bullied if they are a bit different from the "norm", while on the other hand, they have to work out whether a child is just "acting up" to be like their peers or to get attention. It's quite a tightrope for them to walk. Governments interfering in schools probably makes the situation much worse.
