I flagged this question using the "Other (needs moderator attention)" option, and in the textbox I put
User seems to be posting answers to quizzes in a place where other students can easily access it.
And that's exactly what it looked like. It was just a paste of several quizzes' questions with their answers filled out. My guess is that the user was putting it there so some of his classmates could quickly copy it and use the answers for themselves. So not only was it not a question in any form, but it was (in my mind) cheating, and clearly needed to be deleted rather than just put on hold. Even the title, "Disregard this post", sounds like the user knew he was doing something wrong and didn't want undue attention. And in fact, this question was removed from Stack Overflow for reasons of moderation.
However, my flag was declined with the reason
declined - flags should only be used to make moderators aware of content that requires their intervention
I believe that the post required moderator attention, so I'm unsure of why the flag was declined. The post was removed very shortly after I flagged it, as in just a few seconds, so it is possible that it was declined because the post had already been dealt with by the time a moderator got to my flag? Or was there simply a different flag that was better suited for the situation? Maybe I misunderstand some of the flags' reasons, but I didn't see any that really fit in this case, so if there was a better choice I would appreciate being told so that I can get better at flagging correctly.
