[Edit: Richard is stepping down. This was NOT the desired outcome, here. At most, I hoped for clarified policies: a learning opportunity, not a blame-and-punishment game. I really hope this question was not a major part of the decision. If it was... I feel unable to ever question mod actions if the reaction against the mod is so heavy.]
Were the Moon landings faked in Interstellar? has been edited by Moderator @Richard, from "Is there proof that the United States land landed on the moon in Interstellar?" to "were the moon landings faked?"
Richard knew that this would be contentious and misleading, commenting
"I've changed the title. You'll get more upvotes, but with such a provocative header you'll also attract some crazies. Flag anything that looks amiss :-)"
"Per my message above, if you wish to discuss the title, please do so in chat. Further attempts to edit tags into the title will be frowned upon."
Since the only tag on the question was "Interstellar" this second comment was a clear threat of Moderator action to anyone editing the title to mention the word "Interstellar".
After the question hit the HNQ list, the question's OP, @PremierBromanov went to chat (http://chat.stackexchange.com/transcript/message/24365359#24365359), agreed that the mod-edited title is "misleading", but claimed it "an attention grabber, but in a good way", "good for attracting attention to our SE".
Can we have a definitive, clear ruling? Is it:
Deliberately misleading clickbait for upvotes is OK and encouraged on this SE. The mods commit to defending these;
The above is true, but it's only for the mods to make "lulz"y edits to questions: regular users will still get in trouble if exploiting the system;
Something else? (what?)
[Edit, because I feel it's not very obvious from my probably-overly-provocative phrasing above: I absolutely believe that there was not one iota of malice or ill-intent in Richard's modding there, and that he acted with the interests of the SE in mind. I'm very confident that I'd make many far worse calls in his place.]
