A really poor-formatted question was being asked on the main site. I honeslt was tempted to flag it as spam! Do we need to perform large edit on a question like that as it has been done, or is it better to close it and wait for the OP to delete it? On other SE sites, they close such a question as NARQ but when we discussed it in chat, people tend to disagree and preferred to keep the question. What's the site policy?
As far as I'm aware, spam is usually defined as having no legitimate content and a malicious (or at least intentionally obnoxious) purpose. While certainly poorly-asked, this question has legitimate mathematical content, and did not seem intentionally obnoxious to me--there are forums on which this is considered a legitimate way to pose a question, although 468 z's is a little excessive by any standard. Of course, that doesn't make it a good question, and if a user had a history of posing such questions I would vote to close as NARQ. But we try to be friendly to new users here, who often have little understanding of the community and would only be scared away by their posts being closed instead of learning how to ask better questions which can ultimately contribute to the site. While this is my personal take, thanks to a number of hours here on meta I believe the general view is shared by the community; although as Willie points out this is not official policy.
This is closely related to the discussion in Arturo's question, which should give you an indication of the community's stance on these questions coming from new users.
As an aside: we do not have to wait for the user to delete their question after it has been closed. A closed question can be deleted if 3 10k+ users vote to do so or if a moderator takes action.
@Gigili has a very good point, regarding standards for a chat room versus a Q&A site. In fact, I don't think many chat rooms would consider entries that included
plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz answer me sooooooooooooooooooooooooooooooooooooooooooooooon
to be acceptable behavior.
The individual who posted the above mentioned question has returned to ask a second question: Relationship between $\nabla\cdot n$ and the normal $n$
So far, he seems to be able to understand English and Q&A adequately well to provide affirmation when respondents answer his questions, and reformat for him. However, he doesn't choose to select an answer.
Is this trolling, spam, lack of familiarity with Q&A standards? I don't know. User is not registered, says his geographical location is Iran. Internet users in Iran are not ignorant! Most have good manners just like the rest of the internet.
