I have this specific question in mind.
I agree that the question is clearly missing context. The contributor showed no effort, gave no context, and did not try anything to solve the question.
However, one comment basically gave the answer (see the comment with the most upvotes, from @logarithm). As the contributor is new, they is quite high a chance that he won't bother rephrasing the question, or improve it. And we are left with a poor written question, nonetheless interesting for beginners, and for which nobody can post an answer.
Wouldn't it be more useful for the community to let someone give a well-written answer? I've seen quite a lot of questions staying [on hold] forever while an easy answer would be helpful to some people.
