No. What they are referring to is a seperation in media consumption, not the blocking of specific media.
I know your concern but my question is ultimately about personal preference over actual standard or expectation. If I were to say that porn itself on lemmy should be it’s own, privately accessible entity would be defederation (even though that is not a word in the lexicon. Closest would be anti-federalist). Plus, me personally, I’m getting the impressions that you are trying to say that it should be expected to look at porn which is not the case. I can personally choose to avoid it if I want to. I’m not asking to shut it down
