Instead of inflicting PTSD on content moderators, why not give the job to someone who actually wants to see this type of content? They must exist, otherwise the content wouldn't spread in the first place.

And/or crowdsource it so that more people are spending less time doing it? Viewing a little bit of this content is probably less traumatic than viewing it for 40 hours a week.

Of course I realize it'd probably be a regulatory minefield, a thorny area morally, and any specific plan would likely draw critics. But it seems a lot better to me than scarring people for life with a full time barrage of things that repulse them.

For instance, why not offer convicted pedophiles jobs which involve screening out child porn? That would save an innocent person from the trauma involved and it might even allow the pedophile to feel like he was redeeming himself to some degree by saving others from viewing that material. From my understanding many people with that fetish feel a lot of remorse about it and they're not exactly trying to get other people into it.
