There was the bit which prompted my first message, where you said "DON'T

That's has to do with the fact that he asked a valid question, I and
several other people answered it somewhat uniformly, and then he
proceeded to refute that answer in a different thread. (I'm not going to
look it up.)

I understand the context (and the sentiment behind it; really!) but I just
think that when it gets to this level it ends up being counterproductive.

But I never said anybody "wasn't allowed" to disagree with me simply
because of my credentials.

Well, you told him not to, same effect in the end.

Apparently not. He's still posting here, isn't he? I simply threw him
back into the killfile and will not answer any further questions he asks
unless he pays me for ground instruction.

If there's a problem with that, too bad, I guess. Choosing to ignore
all further questions he asks is entirely my decision. If he chooses to
spout bull**** in a student forum as if he was some sort of authority on
the matter, it's equally my right to illuminate the fact that he's a
fraud and that I'm not.

I think this is a good decision. Refuting him *can* be useful, but in my
opinion only until it reaches the point where he's obviously being
ridiculous, at which point you just have to let him be, because otherwise
you'll never reach the end of it. Killfiling him is a fine alternative,
though.

There's a great comic on this subject: http://xkcd.com/386/

Ultimately you have to just give up and let the troll be wrong.
