I just realized that a question of mine was deleted by community. In contrast to this meta-question there were neither downvotes nor am I deleted. Since this happened around one year after I posted the question, I suspect there is some automatism around pruning unanswered questions with no upvotes. Is that assumption correct?
It is not exactly my best question, if it is not worth keeping, so be it. However I am irritated by the fact that there was no notification whatsoever that a) this was going to happen and b) afterwards. Had I not linked to my question in a related one of mine I would not even have noticed (except for one day wondering "Didn't I ask something about inside-out Laurent series on math.SE?" and probably asking it again in more or less identical form), and lacking 10k rep I wouldn't even have the link to it. As a matter of fact, the deleted recent questions doesn't even show that up - it might be more helpful to have a list of recently deleted questions instead. Since deletion is quite a severe "modification" to a question, should the Community-user really hold such fully automated power? Shouldn't this require at least a review by a meatbag-entity?
