Everyone is assuming OP is meaning ML and that they're in the just-enough-knowledge-to-be-dangerous phase. The problem that needs solving isn't "catch anything that could, upon deciphering, hurt someone's feelings a bit". It's "catch enough despicable or aggressive comments before they cause problems for others". The later is easily doable because part of the signal is the interactions and you only need to damp bad interactions down until they aren't self-sustaining wars across the feeds of the uninterested, not sanitize every post so that they're all toddler-safe. Once you stop trying to prevent bad thoughts and switch to trying to create a good forum it becomes tractable at any scale.
