Sorry but anonymity and resistance to takedown orders is not solvable by technology. What you are asking for is basically for tech to let you violate applicable laws. Whether the law is good or bad is another story but as long as that law is in force this sort of requirement is a mirage. Server operators don't exist and live in a vacuum, when they get services blocked, servers seized and prison sentences imposed for not cooperating with lawfully issued orders (such as a subpoeana to identify a criminal using the service), then what? All that is happening already. If you want to deal with unlawful orders of this kind or abuse by the authorities then the technology is the wrong battlefield to fight this. This has to be done in parliaments, not server rooms.
