@Elizafox hi Elizabeth: I work for the EFF, though I'm not a lawyer, and this isn't legal advice, and more of a question. Do you remember where you got the idea that the CDA 230 safe harbor doesn't apply to moderated content? It was originally drafted specifically to permit moderation by hosts, so that interpretation surprises me.
(Note that this isn't about CP, or simulated CP which -- because of the potential for criminal prosecution -- is covered by different laws.)
