Stopping anonymity does not meaningfully prevent bullying. Internet anonymity is not essentially to bullying: it can be done through a nearly infinite number of media. Importantly, it is not even essential to anonymous bullying. For example, it is quite simple to send anonymous text messages: all that is required is access to a phone that the victim does not have the number of. It is similarly easy to simply write notes or letters, and leave them in places where the victim will find them. Anonymous posting on the internet is far from the only place where these kinds of anonymous attacks are possible.  All this policy does is shifts the bullying into areas where they may be more difficult to monitor. Rather than sending messages online that can be, albeit with some difficulty, traced back to the perpetrator, or at least used as some kind of evidence, bullies are likely to return to covert classroom bullying that can be much more difficult to identify.
