Well, you have to understand. Once someone has spent as much time in forums like these as some of these guys have, they've seen every type of troll you could imagine. An introductory post with a little about the person and their machine is simply just proper manners for internet forums of all types. They were simply giving back the rudeness of the original post. It was even explained (in a sarcastic way) the reasons they were being rude. No introductory post, no previous input to the community, no hello, no thank you, just a plain & rude "I have this code, tell me how to fix it" (not an exact quote, my grammar is better).
When seeking free help, one should be careful not to offend those they're seeking the help from.
Now, that said, I'm not excusing the replies in any way (two wrongs NEVER make a right). I think the proper manners of such things should have been explained in a non-hostle way, leading by example and showing proper manners.
It's one of those times everyone is better off keeping to the old addage "If you have nothing nice to say, say nothing at all"... After all, "tis better to be thought of as a fool than say something and remove all doubt".
