What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question

  3. Your voice helps shape the way Stack Exchange operates

Do 10k (and moderator) users have the ability to read deleted comments (are comments deleted forever, or never really deleted like questions and answers)?

No, 10k+ users cannot read deleted comments, so a deleted comment is as good as gone.

The comments do, however, still exist in the database and ♦ moderators can read them and see who deleted them should an issue arise.

Do they end up in the data dump? – Adam Davis Dec 11 '09 at 4:27
@Pollyanna: I imagine only non-deleted comments appear in the dump – Kyle Cronin Dec 11 '09 at 4:28
At least some of the previous data dumps have included comments (including those with Bad Words). – Tom Hawtin - tackline Dec 11 '09 at 17:13
(Indeed, @Pollyanna, in the past deleted comments erroneously showed in the data dump: Data dump includes deleted comments.) – Arjan Mar 9 '11 at 11:47
According to Michael Mrozek in a comment: This is out of date now; it's possible for mods to see deleted comments, but they have to ask for them specially (they're hidden normally) – Arjan Jun 25 '11 at 13:17
@Arjan: Confirmed (I'm a mod), and answer updated. You can remove your comments now. :-) I've also voted to close the other question as a duplicate of this one. There's not much point in having both of them around. – Cody Gray Apr 17 '12 at 6:35

No, we (10k+ users) don't have that ability. They are as good as deleted forever (at least to non-moderators—those diamond folk can still see them).

According to Michael Mrozek in a comment, moderators can now see deleted comments if they want to. – Arjan Jun 25 '11 at 13:21
