When a post is moved to a new topic, the followers (those who watched the topic) of the original topic becomes automatically followers of the new topic (the moved reply).
while the notification level for the new topic should be set to Normal for users other than the original poster.
Continuing the discussion from I get notifications for topics I haven't chosen
This is by design, @gerhard recently worked on this. The users expressed the will to watch the original topic so we assume they want to watch the new topic.
aha, thanks for the declaration.
I can argue that most of the times, they don’t. because the new topic is something that doesn’t fit in the old one, otherwise it won’t get moved into a new topic.
I can share our user experience on this:
as a user during the past week, I was getting some notifications I didn’t want to! this happened for some of users as well, described in this topic: https://meta.discourse.org/t/i-get-notifications-for-topics-i-havent-chosen/129187.
our users complained us about it as we have violated their privacy by sending them notifications they didn’t chose to received!
I think privacy violation here is a bit extreme of a position to take here.
Going to leave this to @codinghorror to decide, I am on a fence. May take him a while to reply here as he is out.
Assuming:
User (A,B,C,D) are watching topic X
User B posts
User C posts
User D posts
Mod splits off B,C to topic Y
Option 1 (currently happening)
A,B,C,D are now watching topic Y
Option 2
B,C are now watching topic Y (A,D are not)
Option 3
(something else) B,C watching topic Y, A,D tracking?
Jeff your call as to what you want here.
I agree that this is not a privacy violation, no matter how loud they state it. But I liked that post because of this logic:
So only the posters who are already discussing something different should watch the new topic:
I corrected the option by changing B to D
maybe I’m using a wrong word/context. their criticism was of course for us, and not to discourse. what they have said to us was this:
we feel that you are not respecting our interests, and you’ve forced us to follow some topics from specific users*!
{*we have 2-3 specific users with extra activity in our forum, who sometimes start extra discussion in a topic and we need to move their replies into a new discussion!}
It seems there is only two options on the table, new way or old way, but in both ways the system decides.
I know there are holes in the following ideas, but it is just a compass bearing and not a detailed map.
Perhaps instead of the system deciding a new user option is added that allows a user to decide when a post is moved if they follow those post automatically (I think of this as the passive option).
Another option is that they are prompted when they visit either topic again and choose which of the post they want to continue to be notified. (I think of this as the active option).
I think that subscribing to the new post all users that have been subscribed to the original post is the correct solution, as it is now.
The users have not control of when an admin or mod can split a thread.
If they are interested in the theme of the post that is split, and they are not subscribed to it, they miss the opportunity to read what other people has to say, or even read that post if it is spitted before they read it, so they cannot know if it is of interest for them or not.
If they are subscribed to it and they are not interested, they always have te opportunity of unsubscribing from it.
I agree with Remah, any user whose post got moved to the new topic should watch, everyone else should be left untouched.
@techAPJ can you make this change?

O problema é que, nesta situação, não há uma solução boa ou ruim. Quando os usuários estão assistindo ou acompanhando um tópico específico e uma postagem é movida para outro tópico, alguns usuários desejam ser notificados sobre alterações nesse novo tópico, enquanto outros não.
Decidimos reverter essa alteração e simplificar a base de código, pois esse ajuste adicionou muita complexidade para suportar esse caso de borda. Portanto, quando a postagem é movida, o nível de notificação atual do usuário será mantido no novo tópico.
Discordo.
Quando uma resposta é movida para um novo tópico, isso significa que ela é considerada fora do tópico para a discussão anterior, e é melhor que se torne um novo tópico. Por que os usuários deveriam se interessar por discussões fora do tópico?
Entendido, infelizmente você precisará de um plugin personalizado aqui para alterar isso. A lógica é muito complexa para manter esse caso específico e a mudança estava causando outros bugs graves.
O software não tem como saber se você está separando algo porque:
Poder-se-ia argumentar que, se ninguém se importa com isso, você deveria simplesmente convertê-lo em uma mensagem privada ou excluí-lo.
Exatamente! É por isso que, se uma resposta foi dividida e não foi excluída, significa que vale a pena e outros podem se importar; se escolherem.
Entendi 
Talvez eu tenha escolhido seguir aquele tópico por causa daquela resposta.
Prefiro receber uma notificação a mais do que uma a menos. E sempre posso optar por deixar de seguir o novo tópico depois.
