A relay is unable to omit photos or links to certain sites?
Discussion
It can but that is passive censorship/moderation.
A subreddit has active (human) moderation that makes sure content stays on-topic.
I hear you but the difference is that there can be multiple relays that focus on the same niche so censorship cannot happen in the same capacity. Deplatforming can’t really happen at all since relays have to compete with each other and Nostr is a protocol not a platform.
Also, relays can omit mentions of shitcoins and NFTs like you mentioned in your original post.
