Concerns about public shaming (CoC relevant etc)
I believe that some conflicts resist resolution more when there's a public complaint and a sense of face-saving and shame etc.
Public discussion of conflicts can sometimes feel like a threat and thus lead people to be more defensive. There's also the issue of a permanent-record so to speak which can get in the way of restorative justice and a return to truly full good-standing.
Public discussion can sometimes be enlightening though.
In my ideal world, users could set a preference of whether they would generally rather discuss publicly or privately if they are involved in a conflict, and some deference to that preference would be respected…
I've not settled all my ideas, but the core point is a concern with the harms that come from public shaming online and a desire to see that discouraged.
