# Do deleted answers live forever?

From what I understand a 10K+ user can see all deleted answers. Does a deleted answer remain visible to the 10K+ users forever?

• No. The evolution of Sun will eventually incinerate the Earth, permanently deleting all Math.SE answers. And 10K users themselves, for that matter. – user53153 Mar 4 '13 at 14:40
• @5pm: It is possible that until then human race have escaped the planet and took the SE databases with them. And until then they are all with much much more than 10K reputations so in fact there is no answer which is "deleted". – Asaf Karagila Mar 4 '13 at 15:37
• @5pm: A similar example is when Krypton was destroyed and they sent Kal-El with the KryptonExchange databases (to whom Jor-El had access, being a scientist and all) to teach him about stuff. – Asaf Karagila Mar 4 '13 at 15:39
• Yes, but perhaps noone will be able to find it. MSE disabled some search options related to deleted posts, a year or two ago. If I know the exact number of some post, I can see it, but the numbers are mixed, both questions and answers get them. So going through one by one is next to useless. – Will Jagy Mar 4 '13 at 23:04
• @WillJagy Indeed, my recent experiment found 31721 deleted/migrated posts among all posts numbered 1-312566. Literal decimation. I expected the rate to be higher among older posts, since the questions without upvotes or answers get auto-deleted after a year. Not so. Among the first 200000 posts, 8.7% got deleted/migrated. For the posts numbered 200000+, the deletion/migration rate is 12.7%. I don't think this has to do with any policy shifts, since the numbers are driven by deleted answers, and those are typically self-deleted. – user53153 Mar 5 '13 at 1:01

• And the probability of that request being granted is $0$ unless the user mistakenly included confidential information in the post. – user53153 Mar 4 '13 at 15:46
