I came across a question that didn't meet the guidelines for the site it was posted on. On the site, questions that are based on typos or problems that cannot be reproduced are considered out of scope. As such, I flagged the question as "Question is a typo". My "Needs improvement" flag couldn't be submitted, so this was the only way I could flag the question for closure.
However, I got a message the following day saying: "Declined - flags should only be used to make moderators aware of content that requires their intervention".
The question was later closed for the reason I flagged it as, so it seems my flag was correct.
Why was this flag declined in this case?
