The coordinates show the location, and the person you griefed shall remain anonymous. Your ban time should have only been 3 days, so that must have been a typo on my part. I had recently went back through all my ban records to adjust and confirm ban lengths, so it should have been fixed. Either way, your ban stands because the proof is shown above. Logblock does not lie.
The damage you did was on: 03-24 18:43:46 alduin777 destroyed cobblestone (among other blocks in the area). Destroying blocks that do not belong to you or on are not your property is griefing. I suggest you re-read the rules.
We hope to see you when your ban has expired, so please keep in mind what is and isn't allowed from now on.
Edit: I'm a girl, not a guy.
