but if a journalist was able to track down an individual, surely more could be found through more low-tech investigative means?
In theory, maybe. Worth pointing out though that the journalists behind the CNN piece didn't track that individual down through any particular investigative means...he bizarrely told them exactly where he lived out of the blue one day.
That was the only tangible evidence the entire CNN investigation turned up. There was literally nothing else to investigate, low tech or otherwise.
I guess I’m thinking more about in terms of appeals for victims and then cross referencing those against any media which was uploaded
Remember that the CNN investigation didn't gain access to a cache of media, just a chat group where some users offered such media for sale privately.
It’s shitty that it seems like hoping for some kind of action or investigation is having expectations that are too high.
It's extremely shitty that very little has come of this particular case in terms of justice, but we can't expect the impossible.There was no further action anyone could have taken here, nothing to investigate. It's just one case though, it doesn't mean that nothing is being done about online abuse material.
On the plus side, it's illustrated the ways in which online anonymity can be exploited for criminal purposes, and the need for greater powers to combat them.
