But “publicly posted” discord invites can mean links in streamers profiles, project websites, etc. While anyone can type that website’s URL, it’s generally expected a group of the public would see & follow that invite, e.g. a streamer’s viewers. It’s not a public space like how a shop on the street is a public space.

Plus, even if the server is in Discovery (and thus really publicly advertised), they’re still mostly sorted into 10+ rooms. Just because a library is public, doesn’t mean I should expect Study Room B will be recorded by John Jameson and entered into a public dataset.
