Edit: This rule seems to be much more nuanced and requires more thought than we had put in, please continue to discuss below.
It is NOT in effect at this time but highly recommend for regional subreddits at least.
The above rule has been added to the instance and will be enforced instance wide. This rule is very common within most existing communities where news articles are shared and avoids sensationalizing the story or attempts at steering discussion by the user posting the article.
If I understand the intent and the discussion so far, it seems that you could stop after “No Editorializing Article Titles.” There are lots of ways to edit a title without editorializing.
The discussion makes me think that the words “editing” and “editorializing” are being treated as interchangeable, so a clarifying sentence or two may be necessary.
“Editing the title for clarity and other purposes is fine. Editing the title to express or alter an opinion is not.”
And I agree with what seems to be a popular opinion that leaves actual implementation and enforcement to individual communities and their moderators.
Note: I find “moderation theory,” if such a thing exists, a fascinating topic, but do not yet moderate any community, mostly because it looks like a scary job. I just try to abide by whatever community standards I find and leave communities whose standards stray too far from my own.
