Would you be okay with a 30 day waiting period for posing a news article, that included strict penalties for misinformation/disinformation? Since you have to wait to publish, you have less reason to get things wrong.
A 30-day waiting period on news articles _should_ meaningfully reduce misinformation. A lot of lives are ruined by misinformation/leaks in early news articles that are later disproven and those retractions are rarely covered as widely as the original false news.
