Hi there
it says in this first image you destroyed iron created by lordoftheblock march 5th.
i asked him if you were friends and if you had permission to work on his place and he said he knew you but that no you did not have permission, absolutely not.
I did the command to roll back the grief which resulted in this second shot telling me it was 50 blocks
This is the result after the grief was fixed.
You took 50 blocks from a friend without authorization. That is grief.
see you in 30 days.
