버킷서버로 운영중입니다

groups는 이렇게 되어있고요

# GROUPNAME:COLOUR/PREFIX:COMMANDS:INHERITEDGROUPS:ADMIN/UNRESTRICTED
admins:c:*:mods:2
default:f:/help,/sethome,/home,/spawn,/me,/msg,/kit,/playerlist,/warp,/motd,/compass,/tell,/m,/who,/item,/i,/give,/mc:default:0

오픈서버를 구축 중에 users에 이름이 없는 유저가 들어오면 그 유저는 커맨드는 가능하나 블럭을 놓고 부수는 것이 불가능한 문제가 생겼습니다
매번 추가할 수 도 없는 상황인대 어떻게 해결해야하나요?
리스폰지역하고 관계없이 모든지역에서 안됩니다

General,GroupUsers,Permissions에서 문제가 생긴 거 같은데 어떻게 해결해야 하나요?
