I don’t think so. Some negative content can be valuable. Value isn’t negative or positive because value is subjective. I value posts making fun of statists whereas others might hate it. I think what nostr does do is allow people to connect with those who have similar values. A lot of monero fans like to shit on bitcoin. Bitcoiners think it’s negative but monero fans don’t. They would zap each other on those “negative” posts if monero could integrate into nostr 😂
