[Long Term] New Channel Types

This may seem obvious to you, but as I am someone who has never moderated a group larger than people I would call my friends, can you elaborate on what the function of "evidence preservation" is? Why do you need that? I will also say, I saw the discussions in the Visionary chat regarding this, and I think that it's safe to say people were misunderstanding and misrepresenting what your are proposing here. Privacy is a touchy subject, and I err against retention that I consider unecessary, but it is clear that you thought about the privacy side of this (in the disaccociation, explicit representation in the UI). The main issue for me is: why?
