Oh please, it's obvious what happened here. You did something in the past with your character, and an additional breach of the Kusari law to warrant an extra hard punishment. You thought you could scapegoat us, saying we fine you without any basis, and expecting us to have no proof ready to counter it.
Now that you got exposed, you are trying to cut your losses and start jumping on some weird argument about metagaming. I suggest you apologize to these guys for wasting their time, and then walk away when you still have some dignity left in you.
