If someone posts an inaccurate or untruthful comment that a reasonable person would not rely upon for their safety, I think the correct response is to mute, unfollow or retort (and if it's self-evident, hopefully it's easy to explain why it's inaccurate or link to countered evidence).

However, the imminent apprehension of harm (from a direct, credible or specific threat), does comport with the concept of assault and is grounds for moderation. Likewise, demonstrating proximate cause from someones actions to a specific harm/damages, would also be grounds for censorship.
