Here is a situation. OP asks a questions and tells what he have done, what he have done actually solves the problem, but he is looking for a better way.
And then there is an answer by a random person who suggests... the same thing as OP has done (which is basically useless). One of such completely useless answers can be found here gathering 56 upvotes.
I understand that anyone can upvote whatever he/she wants, but this particular example sounds so strange to me. So what should be done in such case?
