Comment:

 A workaround:
 {{{
 function wp33631_check_for_existing_user_during_site_creation() {
         if ( ! isset( $_REQUEST['action'] ) || 'add-site' !==
 $_REQUEST['action'] ) {
                 return;
         }

         if ( ! email_exists( $_POST['blog']['email'] ) ) {
                 wp_die( 'User does not exist.' );
         }
 }
 add_action( 'admin_init',
 'wp33631_check_for_existing_user_during_site_creation' );
 }}}
