Grief porn is a form of masturbatory frenzy engaged in by the media and politicians when there is some form of disaster. It exploits the basic voyeuristic nature of humans who get their rocks off by feeling good by looking at the suffering of others.
A recent of example of grief porn here in Australia was the mawkish obsession with the four-year-old girl thrown off a bridge by her deranged father, and the ongoing obsession with pictures of the poor girl in the local media. A similar example is the excessive presentation of baby photos of adults children and babies recently incinerated alive in the recent wildfires in Australia.
Mournsturbation is an exploitative process engaged in by the media once they have created sufficient "grief porn" derived from some unfortunate accident or natural disaster.
Having exploited the initial event, the media then engage in a repetive masturbatory frenzy exploiting every grief angle to the limit. It is is designed to extend the life of grievous event for the purpose of selling more media.
Examples of mournsturbation include the death of Princess Diana, repetitive display of aircraft flying into the twin towers in New York and the publication of the photographs of children and babies who perished in the recent massive Victorian wildfires. It is faux sentimentality and grief for the purpose of selling more advertisisng
