The amount of abuse taking place daily doesn't seem to be decreasing - there seems to be more reports of this sort of thing happening, so it follows that many people are acting out their fantasies, the NSPCC claims that 5% (20k per year) of all children have been abused at some point - which is a lot of children.
This is not a new issue!
ISTR that some 2000 years ago, Peter of Rome stated (Something along the lines of) "All Sinners may be forgiven except those who harm little children!"
Given that killing and abandoning unwanted children was pretty routine in Roman society I imagine that the "Harm" referred to was somewhat more specific!
