<p>I know how many questions are posted to this website per second. Some questions are repeated or even not clear. However, I experienced that some questions have already had a down vote and I see that these questions may be are interesting for other people  recently or in the future. However, anyone who have eligibility to vote can choose down vote just because this question is not under their interest or maybe not clear for them! Some people also, just flag the question directly even without comment if this question is clear or have other problems asking the author to edit their questions. So, is that right? Is that part of user right to do so? Is there a way that this website can figure out this problem? Is it right to leave this under the personal opinion of the user? I mean I can up vote or down vote as I like!! But I think that shouldn't be happened. </p>
