When regular users delete their questions, users with less than 10,000 reputation that stumble across the link are shown the following message:
Page not found
This question was voluntarily removed by its author.
When other users vote to delete someone's question (or delete it unilaterally with moderator abilities) a different message is shown:
Page not found
This question was removed from Meta Stack Exchange for reasons of moderation. Please refer to the help center for possible explanations why a question might be removed.
Generally speaking, regular users do not have the ability to delete their own questions if there are already upvoted answers posted thereto.
Now what happens when users with moderation powers delete their own posts that already have upvoted answers? While the question was still technically voluntarily removed by its author, I would expect the 404 page to display the other message. This is because the question was not deleted by it's author qua author, but only because someone with moderator powers coincidentally was also the author of the post. The real reason such a post was deleted would indeed be for reasons of moderation, as it was only possible to delete it because of special moderator powers.
However, the opposite is apparently true. The original new Code of Conduct FAQ post was posted by a Community Manager (i.e. someone with full moderation powers), and deleted by the same Community Manager. Had he not been a Community Manager (or moderator) he would not have been able to delete his question. Thus, the question was indeed deleted for reasons of moderation (as was in fact clarified by another Community Manager), and it is apparently merely a coincidence that the one who actually clicked the delete button also happened to be the one who had posted it. When I (as a less-than-10,000-reputation-user) view that question, it tells me that it was voluntarily removed by its author:
Can this be fixed so that the other explanation, which seems to be more accurate, will be displayed instead?
