Is it possible to access deleted questions and answers? Where are links to deleted posts?
Generally, it is not possible to see deleted questions or answers. (If it were, they wouldn't really be deleted, would they?)
Team members can see everything ever, since they have access to the master databases. Diamond moderators and 10k users can see deleted content. 10k users are actually forced to see deleted questions and answers; there's no opt-out. 10k users are not allowed to see deleted comments. There are convenient places in the "tools" section that link to recently closed and recently deleted content to facilitate casting delete and undelete votes; this is what Gamecat was referring to.
Users below 10k may see their own deleted answers to questions that are not deleted. This is done simply by accessing the question at its regular URL and looking for the post with the dark "deleted color" background. Users below 10k may not see any deleted questions, regardless of authorship. They also may not see their own answers to deleted questions.
It's only possible to see deleted posts only if:
- You're a diamond moderator.
- OR You have over 10K reputation.
- OR You are the owner of the deleted post.
But they are not listed anywhere, so are difficult to find, although I understand diamond moderators do have a tool for this (I'm not sure if 10K'ers do or not) so if you really desperately need to find a post of yours that has been deleted you could probably ask the moderator team for help.
Note that URLs to questions do not change, so if you retain the link to a question you can always find it (assuming you meet the criteria above, otherwise you'll just get a not found page).
In addition to the answer of DMA57361.
If you have access to moderation tools (10K reputation), you have a list of recently deleted questions.
