At least at Facebook, my ex who did content moderation said there were individual queues they rotated through. Different kinds of crime, demographic, context. I wonder what the parameters are for twitter's community moderation queue are, and especially how much that offloads the more terrible shit onto the remaining moderators. It broke people at Facebook when they were doing it and caused severe PTSD in them. They at least had variety and days that weren't as bad as the crimes against children days.
