"no account" and "throwaway account" are #nostr superpowers. Use them & build them into clients.

Dont forget "view as". Could help to remind/make users aware of how nostr is public and open
At the very least, build acc switcher into note publishing
These would be awesome options on some kind of key management client. Something that (at the time of posting) allows you to choose your npub and revoke compromised npubs.
We did it at DissentWatch.com - wish more people actually used it.
