That's a good find on your part, and pretty accurate, I would say.
The basic problem is that open access newsgroups make it too easy for
those who are mentally ill or have other personality issues to ease
their pains by inflicting them on others instead. It does seem to have
got a lot worse in the last 6 months though. We have the poster who
seems clearly mentally ill with his "Please read again" postings of
corrections of corrections of corrections of things that no one was
interested in in the first place. And we have our two religious
nutjobs who are unable to respect others, or grasp that if everyone
used this newsgroup for proselytising their favorite brand of religion
it would be turned into an unbearable ocean of shit rather than the
current (only cesspit sized) pile of turd, and at least one of whom is
also dim and suffers from the delusion that he should be "leading" C++
(whatever that may mean).
And we now also seem to have acquired this Jeff guy who cross-posts
random garbage to this newsgroup in classic troll mode. And we have a
different poster (strangely silent for the last 4 or so weeks) who will
join any argument which he doesn't understand and take it to the point
of absurdity, cannot bear not to have the last word and doesn't mind
projecting himself as a complete dickhead.
I used to think that this newsgroup had enough sensible on topic
posting about C++ to survive all this. Now I am not so sure.
But I guess some things can still get better. Some may remember the
"plink" days. That particular individual seems to have completely
reformed.
