Whether to add it to the formal guidelines (https://news.ycombinator.com/newsguidelines.html) is a different question, of course. I'm reluctant to do that, partly because it arguably follows from what's there, partly because this is still a pretty fuzzy area that is rapidly evolving, and partly because the community is currently handling this issue pretty well. This may change of course.
One important thing to know: plenty of things not allowed in HN don't show up explicitly in the site guidelines. They are in no way a comprehensive list!
