If Alice makes a followers-only post, and Bob replies to it, to whom should Bob's reply be visible?

@flippac so, the conversation audience keeps getting smaller and smaller?

@stephaniepixie @mayintoronto I think "followers only" only makes sense if you manually approve followers.

@evan Twitter / X have public replies from B visible to A's followers as they are open. But, B's followers can see the response, which is where things get to be problematic.

I wasn't intending to say only B's followers saw the reply, but that they could see the response to a private account.

Marketers, stalkers, and worse have easy pickings in that model.

What @dahukanna lays out in the venn diagram is the good approach.

@evan this is what happens when people want to have a moderately private conversation, yeah: think of it like the pub/bar/café table filling up for a given subthread

@evan @mayintoronto I actually do manually approve but I’m not chatty with every single person who follows me. I don’t always follow back.

@evan I’ve always leaned toward having A's wishes respected as a first order priority.

I've worked to help platforms work through options for B to respond in a manner (it was a two tiered response model) where the one to A is clear, but one that filters out A from the response (either as script to remove it, or giving B the option for a public version).

These options were never implimented.

I know Traction software (for enterprise and “secure" focussed organizations) did this really well.

@mayintoronto @evan Yes! I would commit crimes for mutuals only posts to be an option, here and on most other platforms I use. Followers only isn't always enough.

@maj does this help?

@stephaniepixie @mayintoronto @evan followers only mostly acts as a "can't be boosted" technique imo. the audience limitation is secondary.

side note: why are boost controls and audience controls the same thing! bothers me to no end

@flippac it's not how most other social networks work. If Alice posted a private photo on Instagram, and Bob commented, Alice's other followers could see Bob's comment, but Bob's followers could not.

@evan@cosocial.ca if Bob is malicious, he could simply screenshot Alice's post and share it with his followers.

With that in mind, it seems reasonable for his reply to be sent to his followers, with an off-by-default checkbox to also forward Alice's message to his followers.

People who don't follow Bob probably shouldn't see Bob's reply. But if Alice appreciates it, she could have an option to forward it to her followers (except any who have blocked Bob). Or maybe if she gives it a / (and it's a non-private message) then it's automatically sent to her followers?

It would also make sense for Charlie to have a profile-wide option to not see replies to posts that he can't see. Even if I'm interested in Bob, I don't need to see his reply to an invisible post by Alice.

I realise that has some uncomfortable implications, but as you describe, all of the options seem to. That's what makes it a tough question 

@evan yeah, but we actually have an opportunity to have at least one mode work that way whereas the current effect of "followers only" is for everybody to have to ask themselves if someone is following them who shouldn't be party to the conversation

@evan ("private" here being the DM analogue, ofc)

@stephaniepixie @mayintoronto @evan
Yes! Mutuals Only would be a great feature. I don't think it's possible to express in current ActivityPub, but that could be solved by introducing a Mutuals Collection, or set arithmetic for existing Collections (to: (Followers AND Follows)).

@evan I chose Alice's followers on the understanding that "should" means "what I would expect to happen as a user and how I would want to strive to make it work as an implementor, even though I think that's not now it works now"

This is on the basis that I believe the replies to a standalone post belong "in the space" of that user's posts, and so they should "live" on their instance, and they should have ability to moderate within that space.

@inherentlee @mayintoronto @evan Yes, I mainly only use “followers only so it can’t be boosted”.
It never occurred to me to think of boost control as a potentially separate thing. That would be a good feature even in public posts.

@evan xitter not working that way was also the source of some easy social faux pas if you so much as forgot that one of the people in a thread had their account locked while you were looking at an individual post (in which case in practice you should stay out of it)

@evan The venn intersection of Alice and Bob's followers.

@mhoye so, as the conversation goes on, the audience gets smaller and smaller?

@evan (in general i'm a big fan of making "spaces" with clear scope and privacy rules that, once you're in them, you're in a little community.

on the small scale: people who can see a post and engage with replies to it

on the medium scale: private and public groups/forums with moderatable membership

on the large scale: instance-level communities

vs just stringing together a graph of connected individual posts)
