Please make a new post, @ri-kun. This one is two months old and is on a different topic. We’ll reply in the other post, but what I think you need to do is go in and remove everyone from the root blog (they’ll be assigned as a ‘contributor’ or other user role by default). An alternative would be to edit the template so it always skips that item; I’m not sure what the consequence of removing that default user role would be.
