I think your view of servers here is wrong. They are literally named communities, as in private spaces. You get access if you’re part of that community, otherwise you don’t.
Discord servers are not public websites or a wiki anyone can access, they are not supposed to be.
IRC is a tiny bit more open, but even there you need to join a channel to read it and you can get kicked out. For reading the logs a bot saved away you might need an account too (but that’s up to the server admin or whoever is hosting that content).
