I’ve seen this happen a bunch of time now that people just ask a question and it’s deleted a day or so later. Do they delete the question themselves, or is that some automatic thing? If they do it themselves, why?
*edit*
Thanks for the great answers so far. Very insightful. Please keep them coming, I’m curious to more points of view.
I’ve done it once asking a question. However once I got my answer and I edited my post with “solved with (insert reply from one of comments)” and people still replied with the same answers for a few days with slight variations. I got fed up with notifications and deleted the post.
