RSSHub's guid is the timeline entry's own id (a retweet's id), so ids follow the order the account posted, while feed order and pubDate follow the original tweet. A fresh retweet of an old post can sort to the bottom; it is now posted, and only ids older than every known one are treated as deletion slide-ins. !leaks sorts by id too.
