Why did this post show up, after I ignored the thread?
Something to do with this poster constantly crossposting?

And nymshifting.

Threading is mainly done with References: line, which has
a ~1000 character limit. The sub-thread in this case, has
sufficient MID entries, to be associated with the main
thread. An Ignore-Thread should have worked.

Threading is weakly based on Subject, in that if the
References: line is empty, a bunch of posts with "Help"
as the Subject: , could be presented as if they were
the same thread.

I don't think anything else matters when it comes
to the topic of threading, because we do have
posters who change subject mid-thread, and
that never seems to throw off the reader.

The sub-thread in question *is* missing a Google Groups posting.
Maybe that has affected the "math" the reader uses
to judge whether it's a new thread or something.
Looking backwards and noticing there's a gap
and that upsets the "math". I'm really surprised
readers don't place a Missing entry on the screen,
to represent an item that is nominally threaded,
but is not available in the spool.

It seems Mixmin treats Google a bit differently than
the other servers do.

Arlan Holder's (a.k.a. "Good Guy") post shows up as messed up here on
Eternal September.

On Astraweb, his post shows up as the second original post in the
thread, after his first, even though it is supposed to be replying to
somebody.

I'm convinced the poster is Good Guy. He acts like he's on a mission
to serve Microsoft (just like Good Guy). Constantly shilling for
Microsoft (including trolling the Apple groups). If not being paid,
he's loony.

This "Arlan Holder" stuff is his attempt to drop the HTML, going
incognito, trying to save face.

Notice how well he takes correction...
Just like Good Guy responded so well to the HTML criticism from
EVERYBODY.
