If the question is on topic and generally fits the site, it should stay.

A question with a trivial answer can always be put on hold as too localized, for example:

> This describes a problem that can't be reproduced that seemingly went away on its own or was only relevant to a very specific period of time. It's off-topic as it's unlikely to help future readers.

If this happens to your answer, ask a moderator to undelete the question.
