I think it is hard to tell with what intention a contest-type question is posted -- it may show interest in mathematics as you say, but it may also be an attempt to cheat in some competition, or whatever else. -- We can't read minds, in the end.
@Asaf: Of course as everything you do, also what you post on MathOverflow contributes to how people see you. But what the points on this site measure is just a rough expression of how valuable people find your contributions to this site, and not more.
I see. -- Indeed there is a notable difference between MO tags and the MSC -- among the former there is no hierarchy. Maybe this difference is worth to be mentioned explictly.
