I would imagine accountability is WHY some things don't get answered. Reps can't just post willy-nilly, answers that represent the company need to be approved by higher ups, sometimes the company policy is "don't answer questions about [blank]" - rather than give an unpopular response, etc.
I'm not saying it was the case with your marble question (though since they are items that can't be traded, AH'd, or delivered, I never saw a reason why a transfer would affect them), but I've had friends who were official company reps on forums. I watched them sigh at question they were forbidden from touching, not to mention odd half-answers that were the official line. And in one case, I wasn't a rep, but people knew who I worked for - and I almost got into HUGE trouble over a post that you would read and think "who gives a crap!"
It's a job with lots of restrictions and pitfalls and what amounts to an impossible-to-please user base.
