With all due respect to JCH's desire to improve himself and the world, because what he's saying is obviously poorly presented and often wrong. _Anything_ said on the internet or Usenet should be taken with a huge grain of salt, so there's no reason to flog the subject if a presenter won't listen.
Frankly, I just don't see myself as having the responsibility for chasing after all the people giving bad advise on Usenet. If I see someone giving advise contrary to what I would do in response to a question I'll respond, and let the original poster decide which answer to believe.
But someone who's just spontaneously posting cracked "tutorials" usually doesn't yield a very high effect:effort ratio, as you're finding. Since I have faith that one doesn't need to know differential calculus to recognize BS when one sees it, I don't feel a driving need to respond to his sort of posts.
It would be different if he posted his stuff, asked "oh experienced folk, what can you tell me about what I've done", then actually _listened_ to the responses (other than to argue). But since his receiver is broken, I see no reason to transmit.
