There are situations where, after a short discussion in comments, a post is edited to reflect the outcome of the discussions. In these cases, I would like the no-longer needed comments to be removed.
Is it enough to flag the first one?, i.e., will moderators systematically go through the other comments to see which need removal? Or is it better to tag all comments individually? (I am concerned to over-burden the moderators when tagging all comments - not sure if it creates more work for them).
