Theoretically, if I was behind enemy lines like that, I'd start by erasing any and all notions that I am, or was ever British. Then, I'd switch away from paypunk and/or massacard and just use monero/sanitized bitcoin. Straight up give the woke gestapo dead ends and fake news to chew on. Make it impossible for them to even find you. They want to genocide you, you don't need to pay them.
