You can flush such lines in a hook:

#+begin_src emacs-lisp
(defun my-flush-old-comment-syntax (backend)
  (while (re-search-forward "^#[^ \t+]" nil t)
    (when (memq (org-element-type (org-element-at-point))
                '(paragraph verse-block))
      (delete-region (line-beginning-position)
                     (progn (forward-line) (point))))))

(add-hook 'org-export-before-parsing-hook 'my-flush-old-comment-syntax)
#+end_src

For a warning, you may want to have something like:

#+begin_src emacs-lisp
(defun my-old-comment-syntax-warning (backend)
  (when (re-search-forward "^#[^ \t+]" nil t)
    (or (yes-or-no-p "Document may contain old-style comment syntax.  Still proceed? ")
        (error "Export aborted"))))

(add-hook 'org-export-before-parsing-hook 'my-old-comment-syntax-warning)
#+end_src

If the error, which you haven't reported yet, happens when using
filladapt, then filladapt has to be tweaked.

I am probably misunderstanding "bug 5". May you describe it again along
with both the expected and actual behaviour in the situation?
