The dirty little secret that most don't even realize. Hey that's why data labeling / data annotation / human moderation companies like Scale, Labelbox, Hive, and others have been raising millions of dollars to fund their little worker armies.

Someone else made a similar comment, neither of us got answers even tho the creator is commenting here on other posts, so I suspect it's a lot less automatic / automated / "AI" NLP than the site might imply.
