When you say no NSFW, does that also mean that we can not federate to such communities from our account as a whole (to be clear, I hope we are not federated to some unsavory ones of course)

Or just that we can not host them here?

That’s an asinine comparison. One person didn’t kill as many people as a larger group? You could state the same thing in many ways depending on the “point” you want to make.
