Decentralized platforms like Nostr can't truly ban anyone, they can only try to hide the content, because once information is published, it's essentially impossible to completely erase it from the internet.

Actual freedom of speech without freedom of reach
Great power, great responsibility. This is both the strength and the weakness of decentralization. Once information is published, it's impossible to erase it completely, and that's the way it is, no other way.
This is considered true for anything that is public on the internet. Especially when the internet archive was in its prime scanning and copying everything it could find on the public web.
The key difference here is that the content is signed. We see screenshots of tweets and archived copies of content, but how can we ever know that the data/screenshots are genuine and undoctored? We must trust that the copies are genuine and that the re-publishers are honest and unwavering in the face of pressures to doctor their data.
With Nostr, all content is signed. As long as we know a person's npub, we can always verify copies of nostr content and prove that it is data created by our person of interest.
This means that if someone wants to twist our words, run a smear campaign, or wants to hide their words by denying their own content, as long as we can find copies of the original content, we can know what is real and what is not.
I am definitely on this train BUT since joining nostr I've got DM's from "Jimmy Song" and "Jack" and at least on primal you can report for impersonation. Granted that's not a true ban or report but I feel like there's a little too much space for these scammers. I don't know what we do about it other than telling them to get fucked.
