This once again brings up the point that while Meta and other "single company" social networks can easily exclude you, you can't get excluded on Nostr.

It's designed in a way that that's not even a thing. Anyone can create account locally on their computer or mobile phone (even completely offline) and that's it. If you save & store your "notes" or "posts", you can always re-broadcast them later to different "relay" servers - and this is what your app can do for you anyway.
