Heck, I've seen an ump in his second year call a fair ball that definitely wasn't so. The ball was hit in the air to the outfield and landed in foul territory, but he called it fair because "it had passed third base in fair territory, and THEN went foul."
No matter how boneheaded the question or ruling, I really don't care if the poster is who they say they are. If they're some kid wanting a ruling, well, what's wrong with giving him the answer? His coach probably doesn't even know, and maybe it gives him a better appreciation for who we are (unless, of course, we run him off by calling him an idiot for posting such a stupid question).
I do IT support for my full-time job, and I've firmly believed that one should never make anyone feel bad for asking questions, no matter how braindead it may seem to me.
