Thanks for the example. I'd be surprised if content screeners are employed with Facebook anywhere in the world. Most don't make that job for a long time and they probably want to avoid being sued for compensation, I could imagine viewing those videos/images without proper training will lead to long-term psychological issues for many. It's easy if FB can just hire a subcontractor that files for bankruptcy once claims come in.
I’ve always been curious as to what “psychological training” would consist of to prepare for seeing such explicit content day in and day out. Perhaps something similar to military/war psychological practices?
Even in the military there is no such thing as this type of training.

Not exactly what you asked for, but similar enough:

More than "training" it is "assistance" and "psychological support".
Nonetheless, when Facebook had to face a small content-related crisis in Germany in 2016, that didn't stop Zuckerberg from saying the the company hires teams of hundreds in Germany to stop the spreading of hate content. They don't.
