I got a rep boost today when someone on Reddit linked to an answer I made 4 years agoan answer I made 4 years ago.
Now that answer was a bit flippant and if I made it today it would definitely be a comment, but after seeing the Reddit thread a Stack Overflow moderator decided that, as a comedy answer it should be deleted.
I don't have a problem with this, it's a community site so this kind of cleanup is expected, if a bit unusual after 4 years. However now the Reddit thread is now also useless as it takes 10k reputation (I think) to see deleted answers.
My suggestion (inspired by one Reddit comment) is that deleted content should be visible to anyone (albeit still identified as deleted) if it is directly linked to, i.e. a link with the specific answer ID provided. My feeling is that because only one such answer can be linked to, the deleted answer should appear in its normal place (as if it was your answer) but I would also agree with arguments that it should be sorted to the bottom (as mods see deleted answers)
EDIT:
As I mentioned in a comment below, I do feel that this feature request ties in with Jeff Atwood's vision of there being a fight against pernicious and pervasive link rot all over the Internet
