I once told my big brother who's acting like 12, that he may NOT use my admin account. Obviously he answered "No, I won't.. You can trust me" But now that meter which was filled by 16 years of trust got tipped over. And he placed a big rock ontop of it, so you can't just lift it up again.
Apparently he had used my account while I was asleep and spawned himself items, aswell as world editing forth a base with over 10'000 anvils as wall.
It's funny how I told a couple of members from the staff that he is 18, soon 19. And all they came back with was: "Wow, are you sure??"
Here's a picture of how the base looks like after we removed the anvils and acouple of other stuff.
