Can't speak for other GiveAwayer, but if an applicant shows genuine concern about my qualification to be his inviter and asks me questions like if information I expose here is isolated enough from ones on the tracker (and even more, like he needs a few days or even weeks before giving me feedback to ensure timing is blurred), I'll be much impressed and chances of choosing him will in fact increase, because he proves he cares and he's less likely an idiot, which matters more.
