Over the last year or two I have encountered a couple of times the situation that I answered a (possibly badly formulated) question on a topic I am expert in (the [gap] tag) as I felt that the question, though badly formulated, was not obvious and a response might help other users later on. A while later the answer disappeared as the user deleted the question (or even their whole account), making the effort on responding disappear. (Often these were users with very low reputation, they might have created throwaway accounts.) Is there a way to make answers in such cases survive (or rescue them)?
When you've got enough reputation that you can see deleted content, type the following command into the search bar:
Searching for deleted content will only show content that you own, so you will immediately see your answers (and your questions if you asked any on the topic) and nothing more.
