"Facebook is taking fresh action to prevent so-called revenge porn from being spread across its platforms."

enorbet, I really do think that we all know what "child pornography" is, and that we can find a reasonable balance so that operators of web-sites upon which such materials are posted can feel the hot breath of the law forcing them to be damn sure that the material doesn't arrive and doesn't stay.

We can't simply say, "you're responsible for whatever you put on my site, and I'm not."

And, we don't need to resort to personal opinions and sensibilities: let's just stick to the things which are already well-defined and so declared to be illegal by the laws that we already have on the books. If someone is using your site to commit a felony, you can be prosecuted as an accessory to the crime. This move is expressly designed to "put you on the hot seat, and keep you there," so that you will prevent these things from happening under your watch.

Yeah, I think that this is quite reasonable. We already have facial recognition. Betcha we can invent porn recognition, too. If we purposely put the site-owners into a legally vulnerable position, we can make a big dent in this reprehensible thing.

By extension, having once been married to a woman who was devastated by abuse probably as far back as the crib, I have experienced what degree of devastation can occur and how far the ripples can spread, so I certainly hope that at some point such aberrations can be culled from the Human Experience. I also hope to at least try to avoid legislation that cures a gangrened leg by amputation at the neck.

In that vein do you have any ideas on how such software might be written? If nobody can define it sufficiently to communicate its identifying attributes to another person, how can we write a recipe for a machine?
