I am fairly new in the Super User community, and I am still trying to understand how things work. So forgive me for asking this question which may seem a bit silly to some members.
This is becoming more and more common. A user creates an account, asks his first question, often without bothering to put enough details into the question or make any effort to find the answer on Google. Typically with multiple formatting mistakes. And then the user disappears straight away. Never bothers to come back and check for answers, upvote/downvote, or mark as solved.
Members spend their time to edit the question up to the standards of Super User. Then members invest their time and effort into answering the question, sometimes also doing some minor research work. Meanwhile author never bothers to attend his post.
Sometimes, if the question is good, and it receives enough attention, then it accumulates enough useful information even without OP's attention. But much more often it is a question of type "How do I get something very obvious and not very useful done in an application X that no one really uses anyway?"
What is the policy about such questions? Are they automatically or manually deleted at some point? Are they a subject to cleanup?
