From Zeroedge:

“Nostr is a new innovation, and there’s a lot to learn. There are aspects you might want to consider about this tech while doing your research and making your own decisions. Since Nostr is not surveilled by any one authority or watchdog, users may need to do more due diligence as they grow comfortable in accepting that responsibility. The Nostr protocol provides a stark, simple contrast to the high levels of censorship and guardrails that we’re used to seeing — which is what makes it an entirely separate entity from “social media” as we know it.”
