You're trying to ban the person with most of our loving supplies over a couple wheat. He didn't take anything valuable, and I offered to give you iron and gold in recompense for the wheat. We have reason to be pissed, you have reason to be mildly annoyed.
Why does he have your supplies? That seems rather insecure, wouldn't you say?
Either way, stop the fighting. I work to maintain a peaceful server where everyone is friends. Fred, we understand your position, and the position of those you believe to be antagonized by Mega. It's a stupid argument, really. Mega, I'll give you the wheat back. Fred, you had no cause to call his home stupid, although I can't imagine he's terribly upset about that.
All in all, the quantity doesn't matter. What matters it that Jesusfish didn't think before he acted, and that's earned him a one day ban. I recommend you don't trust a thief to hang on to your best items, and I don't see why you would have him do that in the first place anyway. But that's not my business.
