Thought I disagree, if the feeling of the policy makers is that old threads should not be replied to and brought into new discussions, then I'd say delete all threads that are prior to whatever date you feel is "too old". You'd be surprised the storage space costs that will be reclaimed.
We tend to close the necroed threads if they are no longer applicable, the conversation isn't driven naturally and isn't contributing to something that is current.
I have let necroed threads run in the past, mostly as the discussion has started up again and the activity in general on the thread is good and related to the original intent of the thread.
I see no problem in resurrecting an old thread if this is the case
