I don't understand what a nostr subreddit is? But if this is something akin to a community/group then I don't see the problem with so called "censorship", but again I don't know what this is.

Censorships is what twitter/facebook, etc. does. Communities have rules, like if someone sets up a group about IDK football and a person joins and wants to talk about politics, kicking them out isn't censorship, just a rule so the community is about the thing it was set up to do.

So what the fuck is a nostr subreddit those two words don't go together for me.
