I understand that questions asking for medical advice are off-topic (as discussed in this meta question) and therefore should be closed.
However, from what I got, there is no clear definition of what a medical advice is. Therefore, I have asked this question to seek a clarification on that close reason.
Now, there's a question that may come up: how should one handle questions that do not objectively fit a closed reason (such as the definition of medical advice) or that may cause doubts if it does or not?
Note that I have used the medical advice here, but the approach may well be generalized to other closed topics.
Should it be given the benefit of the doubt to the user and leave it open?
Should one ask the user for clarification and proceed upon that?
I do see value on the 2) one as I see it will make the community more friendly to new users.
