"Character is what you are in the dark."
—American evangelist Dwight L. Moody, as quoted by Lord John Whorfin in The Adventures of Buckaroo Banzai Across the Eighth Dimension
This. There have been a number of articles written about why the mantra to "do what you love" can be a bad one, and this is one of the reasons. If you're passionate about what you do, many employers will exploit this fact. You'll end up being one of these chumps who works 80+ hours a week, sleeps on the couch in the office, and subsists on leftover Chinese takeout reheated in the office microwave, cold pizza, and Mountain Dew.
Once people get older, they also develop other priorities: a spouse, kids, aging parents, health problems of their own caused by a couple of decades of lack of sleep and eating crap food and not exercising. They realize that no one ever dies wishing they'd spent more time in the office. They start to establish boundaries around their working life so that they can engage in better self-care, and having meaningful relationships with the other people in their lives. It doesn't mean that they're not passionate about what they do any more; it's a sign that they're no longer willing to allow someone else to exploit that passion to another person's profit rather than their own.
From what I've been reading, some of the models were under 18 when the photos were taken, which makes those photos child pornography. Hosting, linking to, uploading, distributing, possessing, or downloading those particular pics is illegal. "Child pornography" is a whole other level of illegality to "stolen pics," with much heavier penalties.
As far as the argument that "Nobody cares until it happens to a celebrity," sometimes a famous case that happens to a celebrity is what people need to get them to start caring about an issue. A lot of people started caring more about AIDS once Rock Hudson and Freddie Mercury died. Nobody really knew what ALS was until Lou Gehrig got it, and it ended his baseball career and then his life. While the events themselves are regrettable, I think it's great that this has started a dialog about stolen pics and revenge porn. Look, there are plenty of people who willingly place themselves on display. Why fap/shlik it to stuff that was posted nonconsensually?
I remember reading about this a while ago, so my memory on this may be somewhat fuzzy.
As I understand it, there's a fairly large database of checksums (MD5, SHA1, whatever) derived from known CP images that's maintained by law enforcement agencies and supplied to large email and hosting providers like Google, MS, Yahoo, etc., for use in detecting such content. If they get a checksum match, they take action. Apparently there's a small enough pool of commonly-circulated images that that approach works fairly well.
I think some news agency some years ago interviewed someone at Google whose job it was to review images to see if they were CP or not. People don't last long because they find the work so traumatizing.
