I don't know how to solve this technically, other than with pure "dumb" relays, and that is only because I think you would have a chance at plausible deniability when they arrest you, at least. But even that may be insufficient, as we're seeing with the kangaroo courts that are being organized to jail people for writing software, as State bureaucracies become more and more brazen and drop all pretense to even act as a law-based regime.
