Since you don't seem to get it we're going around in circles. The situation is simple. You admitted to griefing 50 iron blocks, which means that they are still in your possession as far as I'm concerned. This is how the unban is going to work. I'll unban you and you will set a target of iron to work towards, at this stage given that you are a donor I think between 10 to 20 blocks per week is a decent goal. You will place a locked chest with my name on it on your island, and send me a PM with the coordinates. I will check back weekly to make sure that you are meeting this goal, in essence you'll need to deposit at least that amount of iron in each week.
