I don't agree, if you are just talking about how objectionable those two posts are.
I don't think the reason community moderation, or something similar, is needed, is because people post objectionable things using foul language.
I think the only valid reason for censorship is to stop spam which destroys people's ability to communicate.
Usenet used to be full of crap like this. It was still useful. Its failure was only the overwhelming *amount* of crap.
In nostr that's kinda currently what chat is for. It's got no moderation ability at all. Communities are meant to be highly controlled to stay in topic. So it's more useful for someone who only wants that topic. Think off it as curration and not moderation. It really is essential to make a space that is dense with highly informative content. I'm very pro free speech but communities need moderation to be useful. Otherwise just use hashtags and write hashtag browsing UIs.
This is not the only example, I have a bunch more.
It's not just spam, it's offtopic notes, low effort, engagement farming, corporate promotion, etc.
In the end, it's just content curation. Don't like it? Don't use it, use some other community or start your own. Unlike reddit, no one owns any community "name", it's an entirely free market.
