Human moderation isn’t perfectly consistent, either. It would be extraordinarily expensive to expect YouTube to have humans moderate everything manually.
What are people willing to give up in exchange for a human-moderated version of YouTube? Would we be okay if they charged a $3 “moderation fee” on every upload to cover the cost of paying someone to watch the video and evaluate how it fits YouTube’s rules? The big creators wouldn’t care, but the small time videos would immediately stop being uploaded and competitor websites would become popular overnight.
I don’t see demands for perfect human moderation of YouTube uploads as realistic in any way.
