Usually I don't post on meta. It's existence is useful, but I'm only interested in maths, and not with the kind of social interaction that is customary here. The truth is, I have had a bad experience on Wikipedia, and I decided to never fall into this trap again. Anyway.
The legal question seems to have already been discussed, so I won't argue on this. And I'm almost completely ignorant on this matter.
However, I'm rather surprised by the action taken here to delete a useful question.
This is a good question, indeed. Students may wonder. I once did. So it's by no means an argument to delete the question.
May I recall by the way, that it's a rather accepted use, for a user to post a question because he thinks it's of interest, even if he knows the answer. I have already seen this, and I believe it's explicitly allowed by MSE rules. Even that he answers.
Whatever your reasons to contribute to MSE may be, you are not supposed to only show what you think is worth to be associated to your name, and discreetly hide everything else. Like I commented on the question: this sense of property is alien to usual mathematical thinking, and to the mathematics community in the large. Moreover, MSE is not the place to showcase one's ability. It's not a part of your CV. It feels weird for me to have to write this, but I'm still trying to figure out what this is all about.
But even if you feel like hiding your name, you have already been told it's possible. So I simply don't understand what you want.
Maybe you could clarify, instead of being so imperative. If you don't even think it's worth to explain what you want, why would anybody bother to explain why you may possibly be wrong?
Also, your "I don't want others to respond" is by no means acceptable on MSE, unless you give good motivation for this. Questions are closed when they are off-topic, typically when it's not about maths, or when a student asks people to do their homework. It's not the case here.
- good question
- you are free to unlink your name
- you are free to answer in a better way
