Page owners can now close comments on selected posts. To do so, go to the comment page in question and click the [close comments] link found after the repeat of the initial post. If a comment thread is closed it will still display any previous comments, but it won't show the comment textarea box. To turn it back on: go to the comment thread and click the [open comments] link now found where the [close comments] link was before.
Some old threads are spam magnets. This should take care of that issue.
