It's just a publicity stunt. Some of their questions do not have answers that are both clear and concise because the language specifications themselves are not both clear and concise (in some cases they're neither). It's a classic example of people trying to make themselves look/feel smart by demanding that others' off-the-cuff answers meet a higher standard that their own researched-at-leisure questions. The proof lies in the fact that the answers are language-specific but "SuperCoders" apparently can't meet their own "accurate, clear and concise" standard in identifying that context.
