Anyone who posts on nostr is contributing to the discussion and helping the community grow. It doesn’t matter if they are just here for free bitcoin or popularity. People need incentives to engage.
I’m more concerned about the people who abuse the lack of censorship on nostr to spread hateful or downright abhorrent content. I don’t view the global feed for that reason.
I wish that there was more concern about those issues rather than people being upset that more influencers are using nostr clients to promote themselves.
