Erm, your feed must be particularly bad is all I can say. I do not think you
will change what has been going on since I've been here in the 1990s.
You could make it a moderated group, but who would do the work?At the very
least you would need a moderation bot, and trying to get newsgroups changed
over the whole world so that all new posts go to the moderation address has
been a problem for many years now. If human moderated, the immediacy goes,
and soon or or later so does the moderator leaving the group dead in the
water.
You can kill file people you find tiresome or just learn to sort the
messages .
I do a bit of both, and then sometimes you can still reply to the odd off
topic post if you want. If you use major killfiles though sooner or later
you end up not seeing anybody at all.
It is one of the prices we pay for using newsgroups. However Forum type
systems are the devils work, and I'd much rather have the pollution to
ignore than that draconian inefficient front end any day.

This IS a very interesting NG but this morning there
were 220 messages waiting and there is no way that I
was going to plough through any of them!

Moderate, please ! ! !
