Yeah, this is unfortunately the industry norm. With the cost of storage being so cheap nothing gets deleted, literally nothing.

This is why I think it's advantageous for nostr to lean into what makes it unique.

If a design goal for nostr is to make it censorship resistant, then it should be difficult to delete messages. That is the point of the system.

Therefore it follows that it should not be used to publish information you don't want seen (or stored indefinitely).
