"publisher censoring" is irrelevant when there are infinite publishers available all connected via the same network. You can't be "censored" on Nostr, but a relay is well within its rights to block you (including after user suggestions. "reports", as it were)

If you're on a "single publisher" network (like Twitter):
1. You're asking for it.
2. They own your content, not you, so it's not censoring. It's their property to do what they want with.

If you want to truly be censorship-immune, you must be fully sovereign in your compute and your network.
