alt Hacker Newsthe moderators can choose to remove someone who has joined the community in bad faith
unless you prevent new members from reading the chat history until given permission then they can already read everything before they are kicked out, and they can come back with a different account.
you also can not detect people acting in bad faith if all they do is read.
basically, you can't expect privacy if you don't limit members to people you know and trust. that goes for any group chat, encrypted or not.
i also doubt that discord chatlogs are encrypted on their servers.

This is one of the challenges of building a Discord alternative on atproto. Allow access or not, how moderation works, and having shared ownership that can change.
What is your point? I feel I made the one you are making before you even responded the first time.
That Discord communications can be exfiltrated in this specific set of circumstances (again, something I already said) does little to change that Colibri is implemented in the least privacy preserving way possible, short of publishing directly to every news and intelligence agency on your behalf, and does little to make that very clear in the first place.
