This question: Why do the Japanese wear masks like Surgeons in Tokyo? was closed with no down-votes, no discussion, no attempt to clarify for the user how to ask it appropriately, and an incorrect answer left in place. Other than the format, this adhered to the rules in the FAQ.
On the other stack sites, it takes votes to have a question closed, not a single decision maker. There needs to be discussion or agreement.
This could have been phrased,
[title] I'm travelling to Tokyo, should I be wearing a mask?[/title]"
[body] I've seen people.... why is that, and should I do the same? [/body]
And a moderator could have gently nudged the poster to improve the format.
This is a valid question, and I would have answered:
Japan is a small island nation, where politeness as society are held in high regard;
people wear these masks when they are sick or have colds, to prevent the spread of
illness, not because of the quality of the air.
If questions truly don't adhere to the rules, so be it. But this stack site should use the same governance rules that the other stack sites have.
