How does cyberbullying affect the victim's family?

in most cases the parents of a cyber bullied child will not know about it until told by the child or a teacher or someone else involved, this is because the child in question is most likely more technologically able than their parents and either can hide the cyber bullying (from shame/with the intent to carry on 'normally' as if nothing is happening) or has their own personal interface from which they're being bullied, which is not monitored by the parents.

this makes the victims family feel incredibly helpless and frustrated, and on top of which, unable to do anything to help their child because many families don't know where to turn when a younger member is being cyber bullied.

an example of this would be when my sister was being cyber bullied my dad's idea to help her was to "ring facebook and complain".
