I think not only the OP should be notified of the first vote to close (or at least see it!), but there should be a grace period before the question is actually closed (like a period for bounty) to allow the OP or other users to react or comment. If during the grace period the question is upvoted or there are upvoted answers to it, then, say, more reputation should be required to close it (and the closers would think twice I guess). As things are now, the question gets closed in minutes, before anybody could do anything.

@ToddTrimble Great to know it! Still my point is not re-opening my question but an ethical issue that this practice causes, especially with respect to new users like myself. This site is about helping, including helping to formulate the question and helping to gain confidence in fellow users.

@NoahS OOPS, sorry -- probably on other sites I see this link because I have sufficient reputation. Will now edit the text accordingly.

@ToddTrimble Right, thank you! I did not mention this because I suggest to discuss the issue itself, not to unblock my particular post. Now I added a link to the question.
