I suspect that Skynews choose her because she made for good TV.
She was so very different what people would normally expect a troll to be, that this was news in itself. She appeared to be a middle class, late middle aged woman who could appreciate the difference between how to behave and how not to behave, rather than some knuckle-dragging outcast from society.
Its shocking that she died in this way, and terrible for her family. Its also shocking that she should have felt suicidal. However, finding yourself suddenly famous/ infamous has happened to many.
The McCanns are another example of people who find themselves suddenly famous for bad reasons, but yet people who do not know them did not feel enough pity, respect nor decency to leave them alone.Iin fact, some people who only know what they read in the press choose to go online and post things calling on them to suffer “for the rest of their miserable lives”.
