One of the innovations if this network is how it approaches censorship and content curation/discovery. This is integral to scaling a harmonious network.
The network is set up such that users are the algorithm. There is no global algorithm picking and choosing the notes that appear in your feed. The notes from those you follow who are on the same relays as you, appear in your feed in real time. YOU are the algo.
Your phone (client - amethyst or damus etc) connects to the nostr network via relays. These relays take notes posted from one user and passes it on to all the other users also connected to that relay. You are free to connect to or disconnect from any of the relays out there. You can even start your own relay with relative ease if you're technically inclined.
No one is censored at a protocol level (nostr network). You are free to post anything and everything. It is the end user who can choose to block you or for relays to delete your content.
If you don't like one relaying deleting your content, you're free to disconnect and connect to any number of other relays willing to pass on your note. Again, you have to option to create your own relay.
Due to this, content that is offensive or toxic to an end user simply never makes it to that user. The ability to add or delete relays gives you control over the type of content you receive. When you have the freedom to self-curate, natural incentives produces a more harmonious feed tailored to each individual. Zaps incentives the concept of value for value and reinforce to the content creator the type of content that is favored.
If you choose to act in a way that is toxic and universally hated, you have every right to shout as loud as you can into the void.
