Option to address replies to Follower-Only posts to OP's follower collection
Reasoning
- I don't control who follows me, but some people I follow do. This makes it difficult for me to participate in their Follower-Only threads since my replies could be seen by anyone.
- I don't like that it's impossible to read a Follower-Only thread if you don't follow all of the participants.
Federation
- Don't address own follower collection, but instead address OP's follower collection in
bcc
and intersection between OP's follower collection and user's follower collection incc
(not sure how to do the latter when OP and user are on different servers without storing all remote follow collections though). - Make sure
litepub:directMessage
+bcc
being present results in it not showing up as a DM.
Pleroma should already support bcc
since we introduced addressable lists, but I am not sure about Mastodon.
UX
I am not sure. I would want to avoid introducing yet another scope since it's already a mess.
