This is a good precedence. Could it be made clearer in the rules the specific type of question that breaks the rule (e.g. mention one-word answers)? The wording it has now is too broad and is what caused by problem with the rule to begin with. Make it obvious that it’s pretty lenient.
I’m just going to mention though, we should never moderate believing people would know in advance what is missing. The whole point is they don’t know anything on the topic. If we allow one location question, then we should allow all of them, or else we’re only blurring the line further. Having vague rules is a hallmark of poor moderation and bad culture.
