Score on same subject to avoid read message with this subject in future...

[Oleksandr Gavenko <gavenkoa@gmail.com>]

I found useful hide uninterested threads by:

  .emacs:
  (setq gnus-use-adaptive-scoring t)
  (setq gnus-default-adaptive-score-alist
        '(
          (gnus-del-mark (followup -50))
          (gnus-killed-mark (followup -50))
          ))

  all.SCORE:
  (
   (mark-and-expunge -20)
   (thread-mark-and-expunge -20)
   )

and pressing 'T k' or 'k' or 'C-k' or 'C-M-k'. Uninterested parts marked as
killed and when I leave group 'group.ADAPT' file save message-ids of killed
articles and any followups to them didn't showed.

But sometimes threads are broken or group are broken (in case of forum to NNTP
gateway).

So I try to implement killing by subject:

  (defun my-gnus-summary-kill-same-subject (&optional unmark)
    (interactive "P")
    (when (or (not (integerp unmark)) (< 0 unmark))
      (gnus-summary-score-entry
       "subject" (gnus-simplify-subject-fuzzy (gnus-summary-article-subject))
       's (- gnus-score-interactive-default-score) (current-time-string)))
    (gnus-summary-kill-same-subject unmark))
  (eval-after-load 'gnus-summary
    '(define-key gnus-summary-mode-map (kbd "C-k") #'my-gnus-summary-kill-same-subject))

I know about 'I' key binding but it require a lot of typing and attention...

Is that function a good way to hide uninterested threads by subject?
