I'm not sure I understand the question. You can use any skin as long as it follows the rules set out here. Moved to Help & Support
And I also have a side question: What will the mods or admins do if the chests full of booties that are acquired by unfair advantage is locked by the user who did this?
Like I said, you can use ANY skin as long as it follows our rules. If the chest is unlocked and you take items from it, that is legal.
I see. But just to be sure to avoid confusion, what if there is an unfair advantages in the chest locked by the user who owned the unfair advantages stored inside.
Ok. What if the locked chest have an unfair advantages (like the ores and perks earned illegitimately) gained from the user who locked the chest full of the unfair advantage mentioned.
If they're in an unlocked chest they're fair game. If in a locked chest, items unfairly earned may be confiscated by administration before the lock is removed.
