My comment about that was about the forum in general- you're looking at once specific area of a forum, that forums may or may not utilize to begin with. My wiki for example, doesn't really use a question & answer forum for the game it's based on because the game is small and such discussions are done on the game's official forums. Forums are much larger than just Q&A boards.

If you must go into specifics, yes I agree that question & answer threads are an exception to grave-digging rules, but only if the thread remains unanswered. You yourself have also highlighted another issue with this specific forum area in that there is no distinction in board-view to show what threads have or haven't been answered. A crude solution to this, assuming the board is strictly for Q&A threads, is allowing to see locked & unlocked threads in board view- locked ones have been answered whilst open ones haven't. Again, crude, but it's a workaround.
