The irony is strong with this one.

It is the parents' job to explain to the child what spam is and why they should ignore it. Parents should educate their children about the dangers of improvident internet usage. They will not be able to monitor their child's every move and if they stumble upon inappropriate material, which they will, the parent has to put that into perspective. Nobody said parenting is easy..

Obviously you can't supervise your child every second,but that is not what this is about. It's about parents that should take up their responsibilities as a parent instead of trying to put it in the shoes of, in this example, Google.
