You don’t have to understand it for it to be real. The shit they see is way way worse than goatse. For example, a helpless screaming crying child (who may look like the moderator’s own child) getting raped by someone they trust. That and worse gets uploaded, and it’s their job to delete it.

Obviously being in the room with the victim is probably worse, but that doesn’t mean seeing this kind of thing regularly isn’t still enough to do some damage to some people.
