Hi Daniel, can you help me explaining to math.stackexchange.com/users/243301/user243301 (without saying it comes from me) he has to read a real and complex analysis course, instead of asking many questions beyond his level (whose answers cannot be adapted to his level) ?

@DanielFischer @TheGreatDuck AFAIK duplicates contribute to question ban (at least that is how I understand Oded's answer here: Will asking too many duplicate questions lead to a question ban?) But, as explained in another meta.SE post, closing contributes ony very little to the question ban, compared to downvotes: Does marking an earlier question as a duplicate of a newer one harm the asker?

Quote from Shog9's answer: "An old, closed, but well-received question is probably a net positive; a new, open, but heavily-downvoted question is gonna hurt."

@user1952009 answers are not supposed to be "adapted to someone's level". The answer is to be posted as it is correctly. If the user doesn't understand they may ask for clarification. However, they may ask whatever question they please and you may choose to ignore them or answer them at the level they should be known at.

There is no reason to dumb down your answer if the person is asking far too advanced questions. I for one routinely ask questions that probably far under Real Analysis. However, in the same respect, I probably understand those particular concepts (the specific one's im asking about, not RA itself) more than most people on the site. Granted, that's even assuming it's even covered in a real analysis course, but that's beside the point.

people ask advanced questions all the time. Answer them or don't answer them. That's your choice, but we won't go tell someone not to ask questions because "they won't understand the answer". That is absurd.

@TheGreatDuck I think the message you wrote is ~ absurd. I repeat it again : this website is for studying mathematics, nothing more, nothing less. I'm here to learn some mathematics, and user243301 too, now the problem is that I (and we) don't learn so much when answering to him, and he learns even less because those answers aren't adapted to his level.

(sorry for my bad english, hope you understand what I meant)

And I didn't mean banning or threatening him, I just asked if someone (say an Admin) could approve what I told him several times in a more subtle and efficient way
