This question was closed, without answers, and no activity for at least a week, thus it was automatically deleted. Then, it came up on our Meta, and I decided to undelete it, to give more people the chance to evaluate the closure.
However, Community ♦ didn't really like that, and after a few hours it deleted it again. I guess the script didn't count me undeleting as "activity", and since the question fulfilled the auto-deletion criteria, it just killed it again.
That's... not right. Auto-deleted questions can only be undeleted by moderators, and we rarely do something without good reason. The script should either completely ignore questions that have been undeleted, or at the very least recognize the undeletion as significant activity and restart the autodeletion counter.
PS. The last entry in the revision history is a bit... strange.
As Mysticial points out this has been discussed before. Anna thinks this isn't a bug, and:
If the question is worth keeping around, it's worth reopening. I'm not sure why that didn't happen in this case. Judging by the comments, I suspect Double AA was expecting or waiting on some additional community discussion that just didn't happen.
I don't necessarily disagree with that, but at the same time I don't think 17 hours are enough to generate (and conclude) community discussion (on the medium/low traffic sites of the network). A week (i.e resetting the counter) would make a bit more sense, imho.
