I’m not sure people who curse out the staff have any expectations of confidentiality, but I think you’re going to have to take our word on it.
That’s a very selective quoting of the post, which I’m quoting in full here. These are insults of the person making the posts. The rule is that you can attack the arguments, but not the person making the posts. You can characterize an argument or arguing style. I don’t recall any dispensation for “descriptions of posting behavior.” That’s too vague to be useful and would seem to allow for personal insults.
