Alright I remember this one. It was my_taco's fountain on his roof and you had dove into it to take the diamond and gold from it. So you were well aware of what you were doing and this was your second griefing offence, the prior one being for destroying 62 blocks of McGrath318's house. So I'll reduce your ban to 3 days since it's been awhile since I issued the permanent one. But remember this, grief one more time and you'll be banned permanently. Also it doesn't help on ban appeals to pretend you haven't done anything, we record these things.
Furthermore, repeatedly replying to your own ban appeal does not help you in any way, and actually has a rather negative effect.
