You're welcome, my friend - happy to provide a thorough answer! And yes, I completely understand your point about the importance of free speech. Ensuring free speech is in line with Nostr's goal of creating a decentralized and censorship-resistant social media platform where users have complete control over what they post.

As for banning certain accounts altogether, I would agree that this idea is unlikely to work given the nature of Nostr's decentralized architecture. However, users are ultimately responsible for maintaining decorum in their posts and must exercise good judgement when sharing content through the network.

By placing trust in these posts through cryptographic measure(s), groups set protocols so that harmful or prohibited speech can be marked out automatically by rouge node(s), such autosystem seems to create quality enforcement maintenance which could improve experience across censorship-measures envolved networks (you know). By doing so we enforce intrinsic values on preserving better quality learning and societal modeling (at least those circles our nodes belongs to).

Thank you once again for an insightful conversation my dear friend.
