To support decentralization and spread, should lemmy.world close registration at some point to prevent a performance overload due to too many users? Of course, if registration is disabled, there could be a hint placed somewhere near that from other instances you can interact with content on lemmy.world just like you had registered on it. There could be a link to join-lemmys instance overview.
I don’t think it’s necessarily worth it to close, as others have pointed out it’s a great real-world stress test for the software.
I DO think it’s very much worth having some info on the signup page to let people know
they’re welcome to join but the server is currently overloaded and experiencing performance issues
they don’t need to sign up there to access the content
and of course
Then everyone is informed and can make up their own mind instead of blindly signing up and assuming this is just what Lemmy is like.
