Isn't there a way to turn off comments on zombie threads? I've seen a couple crop up today and it's just so pointless dredging up old threads.
Of course it makes sense if people can still search for old threads and read the wise comments of MNers over the years, but why can't you close the thread for comments? I am on a couple of FB pages where the admins stop comments if the post is irrelevant, it just makes sense.
BTW I have checked old threads to see if this issue has already been covered but didn't post on them because they were zombies
