HN guidelines are to post the article's title
except when it's clickbait. Then you should post a more reasonable title with the main finding, which for a clickbait submission, would presumably make it boring and therefore not get upvoted enough to show up on the front page.
> Otherwise please use the original title, unless it is misleading or linkbait; don't editorialize.

Maybe we should emphasize posting different titles for misleading and linkbait articles, and more aggressively flag those articles with linkbait titles even if they are the original title. Also, I don't know if HN already has this, but I think it should prevent submitting titles which contain a question mark; display a message requiring the submitter to edit the title so that it no longer contains a question. Even if people just edit "Why did X do Y?" to "reasons why X did Y", the latter title has the same exact semantics but I think it's an improvement, because it generates less subliminal interaction.
EDIT: just after I posted, this article is #3 on the frontpage: https://news.ycombinator.com/item?id=38708215. This is an example of what I'm talking about: the title is "SSH protects the most sensitive networks. It just got a lot weaker", which is the article's real title, but I think it should be un-clickbait-ified into something like "Terrapin Attack for prefix truncation in SSH". Although also, that article isn't the original source, and said source has been posted a day ago...
