> As it stands, if 20 people are involved in a discussion, and ONE single person decides to block someone, then all of a sudden, the 19 other people in the discussion (+ any other viewers) are now inconvenienced simply because one person had an issue with someone else.
> Bluesky does have a bit of a block culture, and as such, this issue is only going to get worse and worse, and threads are going to get harder and harder to read and follow as more and more people get blocked.
Trying to create a Reddit-like experience around this limitation would be very difficult, as the thread breakage is done server-side so the clients don't even get enough info to reconstruct the conversation.
