I saw this question What is the concept of HandlerThread in Android?
I think it doesn't fit to SO's question format and I think it is a very low quality question but I do not think it should be removed.
Description of very low quality
This question has severe formatting or content problems. This question is unlikely to be salvageable through editing, and might need to be removed.
I could flag it as a not a real question type but I think this question is real and it is not really incomplete and it is not vague, too.It can also be answered and someone already answered it.
Description of not a real question
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form
I could just not flag it, too but I really think it should be flagged not to remove but maybe to close.
How do we decide what type of flag we should send when flagging such kind of questions?
EDIT: It is now closed as a not a real question, but what makes it not a real question?
