Looks like a RemoveAbandonedClosed
deletion; the Help Center says a question is deleted when
If the question was closed more than 9 days ago, and ...
- not closed as a duplicate
- has a score of 0 or less
- is not locked
- has no answers with a score > 0
- has no accepted answer
- has no pending reopen votes
- has not been edited in the past 9 days
... it will be automatically deleted. These are "abandoned closed", and are termed as RemoveAbandonedClosed
.
I'm not 100% sure and you could verify this by checking when the question was closed and when it was deleted by hovering over the "3 months ago" in both banners. With only 9 views it's unlikely to have a positively scoring answer.
It might indeed become hard to find this question as it's not listed on your profile. You can still maintain a reference to it by using the favorites/bookmarks function of your browser.
Even though it is deleted, you can still edit it, since it is not locked. If you think you improved it sufficiently enough to be warranted for reopening and undeletion, you can flag the post for ♦ moderator attention, asking to reopen and undelete it.
