Use case: sometimes I comment on a question. Then I decide to delete it. After let's say 2 minutes the user that posted the question answers my comment but my comment is long gone! His reply to my comment is out of context now because no one can see what that comment is referring to (my deleted comment).  If I chose to delete the comment it could be hidden but stay there allowing me to bring it back. This can be done with deleted answers right now where I can undelete it if I want.

If moderators can view , can we see comments we've deleted? We can see our deleted answers, but why not our deleted comments?

One screenshot will explain it the best:    It shouldn't be there - appeared right after posting the comment. When reloading the page it disappears so something goes awry with the AJAX handling.  Clicking it is reloading the existing comment(s) and open the new comment text box.

No, you can't hocus pocus a comment to be banished to the outer realms of the ether, but there is a short list of words that, if contained within a comment, cause the comment to be removed after a single flag.  Remember when we had a problem with folks brow beating other users about their accept rate? Well, guess what word was tossed into the magic cauldron? That's right, accept(ing).  Earlier today on Judaism, someone wrote a comment that began with:     I'm not accepting that [point totally irrelevant to the green check mark]   It was flagged, and deleted instantly. This isn't a huge problem in and of itself, though we might want to examine if we still need to fire on that particular phrase - the problem here is that a moderator could not undelete the comment. The only time a mod should be preventing from undeleting a comment is if the comment author was the one that deleted it.  Tagging this as a bug as I'm reasonably certain it's just an oversight.  To reproduce:   Leave a comment with a magic word Flag it as a non mod Preform the diamonding ritual, channel the cosmos as a non-developer Weep, as the ashes of your toils lay in ruins before you, powerless to return them to former glory.   Saying please and reloading the page had no effect, so I don't think this is due to the INTERCAL rewrite that we just finished.   Note that this (and the linked question) talk about the "accept" example, but the bug report is about mods not being able to undelete.  Removing "accept" from the list of magic words doesn't fix this bug, just changes one way it's triggered.

I have had to delete a few questions and answers and really wanted to make mods know why I deleted them, as it stands I would have to revive my answer to explain the reason. With questions once its gone its gone.   It would be nice to have a little field that allows you to select why you deleted something:   Eg. "Deleted cause I answered the wrong question", "Deleted cause I made a trivial logic mistake" etc..

Some questions tend to gain a LOT of comments on them, needing to separate follows-up on questions from general comments like "doesn't work for me either."    Unfortunately, the way those comments are hidden means that you could quite easily miss important ones (like follow-up questions) if they weren't up-voted.  One way to alleviate this is to separate out questions about the original post from regular comments on the post.  For example, we have the answer area just below the question. Why not add tabbing to it such that one tab has "answers" and a second tab has "questions for the OP"?    This would solve the second problem where the amount of space available for comments can be restrictive for complicated talk back to the OP.  For example, consider the following question:   There are several actual questions to the OP in the comments section.  There are also several comments that quite frankly aren't questions to the OP and may, or may not, have value.    Regardless of the value of those ancillary comments, I'd really like to see the actual "questions to the op" separated out.

Comments are useful. Many, many posts need some small amount of meta discussion, and comments fulfill this need.   Comments are also noisy and distracting. Occasionally, someone will post an insightful and informative comment that complements the post its attached to... But more often, they're tangential, quickly irrelevant and in the way: stale comments show up first, making newer comments less visible.  The guidance here for a long time has been that comments are transient, . And yet, some do hang around for months or years because .   So let's fix that.   I propose that all comments older than 7 days be hidden by default unless the comment has been up-voted in the past 30 days. Hidden comments should be indicated by a note below the post ("add / show 3 more comments") and made visible to anyone who cares to click it.   This doesn't destroy anything, but it would get it out of the way of most readers - and hopefully encourage folks to edit it into the actual answers as a result.  Note: I previously suggested this . Other  have been . However, I'm not suggesting that comments be automatically deleted, and they should be hidden based purely on the age / activity of the comment itself, not of the post to which they're attached.

The following scenario happened to a question of mine today:   I asked a question to a topic I'm pretty new to. Someone answered the question, it absolutely satisfied my points, so I upvoted and accepted it.   But a few minutes later he got heavily downvoted because (as I understand it) the way he explained the points were completely wrong and they said his words just show he has no clue about the topic.  So he deleted his answer, which made me sad as I thought it will be lost.  But it wasn't.  His answer is still in the question. It has a weak colour, as an answer has of my own after I deleted it. But why? Is this just to me, as I'm the one who upvoted it? Or is it because at the point he deleted it, it was the accepted answer?  And is this just visible to me?  Or anyone can still see it?  And I also noticed he still has the +2 rep he got left from his answer (after downvoting) so is this really a deleted answer?  What's going on?

I answered a question and my answer was: (pick one)   Deleted Converted to a comment Added to my question as an edit   Why was this?  Why was my answer not acceptable?  What is the definition of an acceptable answer on Stack Exchange?

It's sad to upvote a comment on a post that's subsequently updated in a way that renders the comment obsolete and not be able flag it afterwards.  There may well be other cases where one would want to flag an upvoted comment too.  Related:     From November '09:  Note that this was before comment votes could be undone, so one slip and you were stuck.  The suggested solution there is to flag the post instead with a note about which comment to look at which is inelegant and potentially a problem as flagging a post can have repercussions beyond just bringing it to the mods' attention. From June '10:  Also pre-, which is presumed to address the problem, except that it doesn't in this case.     So here it is nearly three years later and this question lingers unresolved.  It's been positively received (no downvotes yet!), but hasn't gotten any developer response.  The problem that this change would address is still a problem.  The UI as implemented is still confusing: flags are generally orthogonal to votes on questions and answers, so why do comments take an either/or approach?  Comments are purposely second-class citizens, but this seems like privileging them--protection for comments that should be removed!

I think you should be notified if anything of yours is deleted or even flagged, preferably with some explanation (even if it's a simple categorisation like #rude, #irrelevant, #incorrect) and who did it.  Recently, a couple of comments of mine vanished without warning or evidence afterwards. I'm fine with deletion, but I think it should be used sparingly and be based on democratic decisions. What's the harm of letting a comment simply sit with no up-votes or responses rather than outright removal? Or allow downvoting and then negatively voted comments are hidden by default?  I get the impression that anything I post could be deleted. Very few people want to be unpopular or do the wrong thing. It takes time to understand what something is about and how best to use it (this site). Whether or not what I posted deserved to be deleted is irrelevant because I got no feedback. No-one can learn without feedback. The number of frivolous comments with many upvotes I've seen shows how inconsistently the rules are applied. A community that gives too much power to highly rated users won't grow but turn stagnant.  Sorry if this was rude, inappropriate or pathetic. I'm aware that similar discussions have occurred. In any case, I'll continue to use the site and move on...

So I've been experiencing this in the last few days: sometimes when someone replies to my comment, and I reply to the reply, then the "add/show 1 more comment" link appears immediately after I post my comment. However, when I click it, it disappears and nothing is shown.  I don't think it's that OP is posting two comments of which he deletes the second one, because this has happened to me several times, even when I was replying within 2-3 seconds.  I do, however, believe that this is more or less the same bug as , except that I don't have to reload the page in order the link to be gone, and I also seem to be getting the erroneous behavior only if I reply to a comment which is itself a reply to an earlier comment of mine.  Unfortunately, I wasn't careful enough to take a screenshot last time this happened, but here's what I am talking about for those who like visual demonstration better:

When I tried to delete a comment after I just deleted another one, the system told me     You can submit a comment vote every five seconds.   The message should be different, right?

Consider the following scenario please:   I see a question and think I have a good answer or comment. I post my answer or comment and move on happily. After couple of hours I see comments that my answer is bad because this and that and it's really bad - I didn't think enough before posting.   The question is: should I delete my post, or leave it be so that people won't repeat my own mistake?

I put a lot of effort in writing comments in a conversation, arguing against one initial comment made by another user. That user finally deleted her original comment, as well as an ulterior one, rendering the whole conversation meaningless to any other potential reader.  I can understand that one would not like traces of its past errors to remain forever visible on the Internet, but it is obvious that everybody is exposing himself to that when posting on Stack&nbsp;Exchange, and should accept the risk. The conversation was polite and, to my mind, interesting – deleting it does not do any good.  I find it rude and disserving to the community to thus break a whole conversation. My comments now seem to spring out of the blue – you can guess what that makes me sound like.  If the deleted comment doesn’t come back, I’ll have to delete my comments and consider my time lost. Maybe I’m wrong in caring about that, and I got too invested in commenting what went a bit off-topic (but not that much).  Still, I find this pretty rude on the part of the deleter – although she did post a comment saying that she deleted her comment (actually, she deleted two).  The conversation is here, right below the original question:   I did read  and . So deleting or flagging my own comments as obsolete seems to be the right thing to do now.  But I’m unhappy with the time wasted, and, most importantly, I disapprove of that user’s behaviour. What can I do? Would I be right to comment that such a deletion is rude?

I'm fairly responsive to comments left on my answers. This often means updating an answer to incorporate new information or questions that have been added in the comments (or edits to the original question).  It would be useful to flag comments as 'addressed by edit', so that they can be deleted by the commentator, or highlighted for pruning by mods - I don't think this is in scope for the usual 'flag comment'.  More contentiously, it might make sense if comments flagged with 'addressed by edit' were automatically suppressed after a suitable period of time has passed - long enough to rule out silliness with duplicate comments being used to steal comment upvotes.  EDIT I'm not convinced that "This would mean that in the long run, you could delete any comments on your posts without involving others" would be a problem. It is a valid point, so the safeguard would be to have a veto, so that when a poster says 'addressed by edit' the commentator can say 'no it isn't'.  I can see there is still an argument that comments add to a SO users (offline) rep, however I believe mods clean-up posts anyway to remove comment noise, so I don't think anything is really lost.  Moving on to the concerns complicating the UI, I happily concede that a flag next to comments would be the wrong place. Presenting a list of comments plus checkbox at edit time would work, and should improve quality (as comments become prompts when editing).

Lets start with a life-like scenario.  User A receives an offensive comment in his inbox from the OP of a question. A then clicks on the notification in order to flag the offending comment. A mod sees the flag and deletes the comment. Shortly after, the question is also deleted. Because A clicked on the notification in the inbox, that notification is still in A's inbox, with the offensive part of the comment still visible. Edit: The flag was marked helpful because the post was deleted, not because the comment was deleted by a mod.  Please note that although the behaviour of the notifications is as it is supposed to be, this does not fix the possible problem of such notifications &quot;hanging around&quot;. User A can't get rid of that comment in any way, and it may be a long time before it is flushed out by new messages. This issue is mentioned in  but it is supposed to be that comments on a post that you own can hang around, not on someone else's post.  is speaking about comments which have not been read and this . To me this seem like an important issue. To have to see an offensive message every time you open your inbox is not a good thing. I can think of two ways in which this problem can be avoided:  Make sure notifications for deleted comments don't hang around (this I'm sure is the easier option) Allow users to delete unwanted notifications (this could be useful, as this would also allow users to remove notifications that they are not interested in, or even just to keep their inbox uncluttered. It would most likely be hard to implement, though.)  What are your thoughts on this?

In short, if the last action on the post is someone posting an answer, it shows "answered [x] minutes ago PosterName". However, deleting and undeleting a different answer (posted earlier) causes it to switch to "modified [x] minutes ago PosterName", even though post deletion and undeletion do not cause bumping. The last action on the post was answering, so it should continue to show as "answered".  For example, I tested this out in the sandbox:  Answer is posted:        30 seconds later, another answer is deleted (and optionally undeleted; or vice versa probably), changing the label but not bumping it:        The behavior that it should be is:    Find the last active post   If the last active post is deleted it should say "modified" If the last active post is not deleted and not edited it should say "answered" If the last active post was edited, it should say "modified". No duh.      Here's my original bug report, which you can probably just skip unless you need another example:  I just posted an answer to a question, then left the page without doing anything else. But it says the last action on the page is me modifying something, with the  (which shows the last activity) redirecting to , as shown below on the  (it's at the top of the list):    (The , under Questions, also shows this problem.)  I didn't modify the answer after posting (not even during the grace period) nor did I do something else that would cause a "modified" bump (protection, close/reopen votes, add bounty, messing with deletion). There were no deleted answers when this happened. I'm not sure if the problem is related to the question having a bounty on it (by the OP, who is deleted).  None of the other activity on the active page shows this problem. (The "modified 10 minutes ago" on the second question is an edit to an answer.)    Since I first posted this question, another user (named ) posted an answer to the exact same question. For some time the listing read "answered X minutes ago", but now it says "modified X minutes ago" even though it points to the same, unedited answer. However, I noticed that there is now a deleted answer which was last edited before 1006a's answer was posted, but was deleted after it was posted. Now I'm wondering if it has anything to do with deletion.
