Users in a Discord server/local community on tools like Discord naturally expect that their actions within that community are private in so far as they trust everyone in the community (including the operator) to keep it so.

By using ATProto, Colibri fundamentally makes all of your communication within any community completely public to everyone on the internet.

That’s fine for something like Twitter, where the product sets the expectation of such a thing. You can imagine how big of an issue this is when you try to do it in a trusted community model. Add on that Discord is used by kids who likely don’t know this and you can see why this is dangerous.

I consider this not only just a liability but bordering negligence. It is fundamentally broken, at an architectural level

I agree that is borderline negligence, and by far the biggest issue with AT and Bsky. Here is what I believe to be the most recent discussion on that topic:

Fair point! A different user has already pointed out that this isn't disclosed enough on the landing page, and I'll be adding a section to clarify that, both on there and in the app itself.

I think one of the replies here already linked the current proposal for private data spaces, which I'm hoping will become implemented later this year. At that point, people will have the option of either having their community be 100% public, or confined to a more Discord-style data storage, where people can still join, but not everyone can "just read" the messages

Just want to chime in with, this does feel very slick, but this was the #1 question I had. I could not determine it from your site, and had to try it out to see.

One major criticism of things like Discord is that they're private, so I don't think that it's inherently disqualifying, some people might even prefer it for that reason. But it's very, very important that you're very clear about this, up front.

I really appreciate you chiming in, no matter how slick! New section has been added, lmk if you'd like to see this adjusted further

any discord server that offers public invites is effectively public.

First, the user knows this when joining a public community.

Second, the moderators can choose to remove someone who has joined the community in bad faith.

Third, it is entirely different than broadcasting every single action taken by every single user in every single community on the entire protocol to anyone with one URL.

the 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.

Private channels in public servers exist. I'm almost entirely on private servers.
