I am not sure whether there exists some kind of objectivity in taking a decision in closing a question. For example my question http://mathoverflow.net/questions/226226/a-symmetric-function was closed stating that "This question does not appear to be about research level mathematics within the scope defined in the help center." I do not understand their definition of "research level mathematics" in this context. It seems like moderators/admins operate with some subjective opinions usually in undeclared groups supporting each other decisions. Very rarely we find some contradictions or major disagreement. If this is my misconception please elaborate your objectivity in taking such decisions?
