It would be a nice little add-on if intelligence spies can reveal countries that posted anonymous post on the newspaper. If I were to put an intelligence spy in country A, and country A posted an anonymous post on 2019/10/06. Then an intelligence spy has a chance to reveal that they posted this Anonymous post (it'll have to have the exact date and time that it was posted to avoid confusion). This isn't really necessary but it can help bust people who post (game-related) threat posts and generally just people who annoy you.
