@recursive: 1) I would require a comment when flagging, which is useful and frequently requested anyway, therefore both parties are always open to being flagged by each other and more importantly by third parties who can observe the interaction and weigh in on who (if either) is in the right. 2) It is not the same as Dan's proposal because it is a one-time action, as opposed to negating someone's entire influence for a week. 3) It is a much simpler change that several people have requested, unlike Dan's proposal which is a social experiment being pushed on people none of whom asked for it and many of whom apparently don't like it (personally I'm neutral/undecided on the merits, but negative on the approach of pushing these kinds of changes from the top).
