Thought about it. Not sure how. A start would be making a good list of all the related leaks, Panama papers, Paradise papers, Pandora papers etc, with links to all the best info sources. I don't even know how to find those links tbh. There's so much leaked data of that type we need a specialized app (doesn't have to be a client, can just copy and paste for input/output) converting pages from other formatting (wikitext, HTML, etc) to nip-54, so humans just have to check the previews and fix the mistakes.
The question is also which relay. Anything hosted in the EU, Russian, or Australia can get easily shut down by the hosting company, for instance, even if the material is not actually illegal.
So how do we set up a relay farm in the middle of the ocean where it isn't under the thumb of any government?
If relays were built to be small, fast and efficient, using a small, fast, and efficient language, and incorporated a DNS alternative, a million+ relays could be run on SBCs. Combined with a desktop application using @jb55's nostrdb, so that 100% uptime isn’t required, it would be damn near unstoppable.
