Hi Cecil,

Usually, the way I marked spam was simply by using B m
(gnus-summary-move-article) and have them moved to my nnml:mail.junk
directory. B m works either with numerical prefixes or with process
marks. This is how I achieved a little bit of automation:

(defun gnus-move-to-junk (&optional n)
  (interactive "P")
  (gnus-summary-move-article n "nnml:mail.junk" nil 'move))

(add-hook 'gnus-startup-hook
          '(lambda () 
             (define-key gnus-summary-mode-map (kbd "j") 'gnus-move-to-junk)))

I remapped the 'j' key as I never used the defualt goto-article
command. 

Hope this helps!
