I was talking of the builtin message-signature function which can be
called automatically or manually using C-c C-w. From what I read it did
look like that these look to not insert into the yanked article but at
the signature marker at the end of the article where the don't conflict
with the yanked article/message.

From what I read the message-mode yank functions took account of not
interfering with the signature. To me it does sound like a bug if
gnus-inews-yank-articles would break the signature.

Looking at comment in message.el:4037
at (message--yank-original-internal (arg)):
;; Add a `message-setup-very-last-hook' here?

It does appear like this a known possible issue.

I assume gnus-message-setup-hook doesn't work either.

Maybe it's worth to look for an existing bug report for possible context
or open a new one.

Anway good that you found a solution.
