ListAdmin: Is list/archive working correctly?

[dn]

For example, have been following the thread "Is there a better way?
[combining f-string, thousands separator, right align]".


Me email (only) client shows a thread of 12 messages.

The OP was @Gilmeh Serda (from an invalid email address). That appears
in the email thread

@Stefan Ram has had two contributions quoted, but no such
original-message has appeared in the thread.


The archive is only showing seven contributions (for some reason Grant's
recent contribution under the different subject line: "Formatting a str
as a number" appears separately, even though it threads as the same
conversation in email)

None of the OP's contributions appear!


IIRC the design has been that it doesn't matter if a contribution comes
from the Newsgroup or the email Discussion List, they are treated the
same. Are Newsgroup contributions being archived (were they ever)?

Is it user-error that some contributions don't appear on the list, but
do appear in replies, or is there perhaps some other cause?

I see 11 messages and none from Stefan. Maybe replies to off list emails?

I also think that list/archive isn't working properly. Very little emails.
Before, this was quite a busy list.

I can't speak about the archives, but I can say that Stefan's posts are discarded automatically since they are opposed
to their words showing up on the list.

I'm posting this on the comp.lang.python Usenet newsgroup.

Stefan Ram's posts to comp.lang.python include several header lines,
including "X-No-Archive: Yes". I presume the software that copies
comp.lang.python posts to python-list pays attention to some of those
header lines. (I personally think it's silly to impose this kind of
restriction. The Usenet group and the mailing list are both public.)

Lawrence D'Oliveiro adds the string "(Posting On Python-List
Prohibited)" to the subject on his articles, for reasons he has
declined to discuss. I don't know whether the software recognizes
that.

Can someone who manages the list software discuss the exact
rules? I suggest that those rules should be documented on
<https://mail.python.org/mailman/listinfo/python-list>.
