The first thing that is needed is to acknowledge that this is a systems problem. There seems to a mode of reply that can be exploited to harass people, without it being visible to the larger community.
As such, it is not just a moderation problem. Rather, it is something that may need to be addressed more systematically.
Again, what really needs to happen is to clearly define the issue, and understand how it is being used to isolate and attack users.
