One of the techniques could be something like a parental check up of the child's phone so they know what they are doing. If the parents did this they would be able to see the child's messages and even search history so they know they won't be bullying someone. Parents are a big role in bullying because they either don't see their children doing it or their children being bullied. It relates because that way everything would be monitored and nothing would go too far if it did happen to escape a parent and bullying began.
