Moderators have easy access to all posts from a user that have been flagged (and how those flags were resolved), and we can see all comments from a user (including deleted ones). This feature request is to give us some insight into (helpful) flags against a user's comments.
If a user has a pattern of problematic posts we'll see that, but I've seen users who leave many rude or non-constructive comments. These get flagged, the moderator who sees the flag cleans them up, and life goes on. It can take a while for the pattern to emerge because each moderator sees only part of the problem -- and has to rely on his memory. Meanwhile, the user continues the activity and it can become more entrenched. It would be better to be able to spot that early so we can talk with the user about it -- a stitch in time and all that.
I would like be able to see that a user's comments had N offensive flags, M not-constructive flags, and so on for the other flag reasons. I can think of two places where this could be put in the interface:
On the flags page, add a summary with the counts by flag type. Again, we only care about flags that were marked helpful. If a user also receives spurious flags, well that's not his fault so shrug. (As pointed out in a comment, we'd also need some indication of timing -- are these recent flags or old?)
On the "all comments" page, add information about flags to each comment. This should be on the page itself, not behind "expander" widgets, so we can search the page easily. Even better, just as we can filter for deleted and undeleted, add filters for flag types.
Option 1 gives us summary information only. Option 2 gives us the details of which comments they were. I don't know which would be easier to implement. Either's fine with me.
We know that the information about the flag exists in the system, because (a) it shows up on the flagging user's "helpful flags" page and (b) it's in the timeline. This is a request to expose that information in a way that allows moderators to more-easily notice users with a pattern of problematic comments.
Just giving us a total number of flagged comments doesn't address the need, because obsolete flags are usually not a sign of trouble. Often, in fact, they're the sign of a helpful user -- the user commented with a question or suggestion, the post actually got fixed, and now the comment no longer applies.
