Consider the following two cases:
The question asked shows no research effort. It could have been easily solved with minimum research from the side of the user who is asking. But it does not belong to homework-and-exercises tag.
The question is unrealistic, that is, it does asks about something that is not feasible in reality, though the question asked is in Physics, and not "too broad", as it does not raise any good discussions.
Which type of flagging should be done for these two cases? In the first case, I could not flag as it does not belong to "Homework problems should ask for...." flag. In the second case, I raised a moderator intervention flag, stating the question is unrealistic, but it was denied.
A request: any moderator or person with high reputation, who can peep into my account and find about which flags I'm talking of, please don't mention it here to avoid unnecessary discussion. If you find out about what I'm talking here (which, of course, you will), please keep it to yourself; rather let's discuss the cases that I've mentioned here.
