Is there a way to have a newsgroup server reject all cross-posted messages?

Many servers limit crossposts to five or fewer.

The cross posting to multiple news groups seems to be the source of much of
the garbage. I suspect the whole newsgroup concept would be improved if
cross posting were automatically eliminated.

Moderation software can be written to set a limit for crossposting.

Individual users can write their own filters to killfile
crossposts automatically.

(I notice this message is
being cross posted !)

Yes. Crossposting has been a standard tool in discussions of
RFDs for a long time. The idea is to let folks in affected
or interested groups find out what is going on as well as
collecting the discussion in a central thread where it is
easily accessible.

It may be a source of annoyance to some in the crossposted
groups. If the subject line is preserved, folks who do not
want to see the discussion can killfile the thread by its
subject line.

Another tool is to use the "followup" header to redirect
replies to a single newsgroup. That can cause troubles, too,
especially for unwary respondents who do not know that their
replies may be going to an entirely different newsgroup.
