This is yet another incidence of the downside of the Internet.
There has always been, and will always be, a section of society who gravitate towards the darker and more tragic aspects of humanity, and whereas years ago, such individuals would exist only in the shadowy hinterland unknown and unsought by the majority of people, the arrival of the Internet gives such individuals access to the world at the click of a button.
We need to simply accept that like a lot of major positives in the development of our world, the Internet has its downside, and this is just one more example of that, and not allow it to intrude into the world the majority of us live in, which has no place for such perverse and inappropriate behaviour.
