@kissane incredible writing, thank you.
One point about the baffling issue of troll servers invisibly brigading in replies, the current one way threads set up forces this situation for every threads post. They can't see what we say about them.
And, after reply visibility is implemented, the question of whether threads will block these troll servers or not seems relevant.
I realise it's not the focus of your article and it's too complex even for this post, but it concerns me quite a bit.
