See replies to your MULTI-posted copy of message in the other group(s)
to which you posted the SAME message.
Learn to cross-post:

A point not made is that N multi-posted copies will consume N times the
disk space for each of the separate copies of the same post.
Cross-posted messages have just *one* copy on the server with links in
the newsgroups back to the same single copy. Multi-posting wastes disk
space on the server. Yes, your post may be small but remember that you
consume N times the space on one server and then do so again on all the
newsgroups servers worldwide. You waste more bandwidth getting N copies
of your multi-posted message distributed to all the newsgroups servers
worldwide. Cross-posting has just one copy of the message on an NNTP
server, and only one copy gets propagated to other NNTP servers.
To those visiting the newsgroups, cross-posting helps them see ALL the
replies from those in the other RELATED newsgroup to which you linked
your post. That way, they don't waste their time duplicating similar
replies.
Don't cross-post to more groups than needed if at all. Many consider
cross-posting to more than 4 groups as rude and may filter out your
post. The more groups you add, the less likely that they are related,
the less accurate or focused are the targeted groups, or some of the
included groups may already be encompassed by an included parent group.
If they are subgroups under a topic, choose whether you will be specific
or general in the targeted groups to which you post. Usenet-ignorants
that shotgun their posts across multiple groups trying to capture as
large an audience as possible will offend netizens with the poor aim.
Multi-posting instead of cross-posting when shotgunning across multiple
groups evidences you as a newbie, troll, or spammer.
