Everything you write here will be saved whether it is stored or HN servers or not. That's just the reality. Some rulings may stop wayback machine but then there still will be tons of archivers accessible through dark web. Text is really cheap to store and that's moderated text where somebody else is already taking care of it not being just a bunch of random characters or somebody's else encrypted backup. It's just that regulations and our culture haven't yet fully catch up.
