Hello Buglet,
Firstly, thank you for the very considerate and well-worded appeal...
I've attached images of what I found at Lazer's home; there was also some grief to the water that isn't shown in the screenshots as it had already been repaired. From the block history timestamps, it appears the grief was done around 1:45 am CST.
Lazer wasn't online when I went to look into the timestamps of the grief so I was unable to get their confirmation that you share their build, but to your credit when I answered the grief ticket and told Lazer whose name was on the grief, they replied ":O", so it did come as a shock to them...
I would like to get this cleared up as fairly as possible. If you do recognize the modifications pictured, please let me know; there's no doubt the grief was done using your account but I'd like to speak with Lazer to see if this was very out of character.
Also, because you're concerned that your account may be compromised, could you go to the site
http://www.whatismyip.com to find your external IP address and send it to me in a private message so I can compare it to the IPs the server has logged from your account? I'd also advise you to immediately change your Minecraft password at minecraft.net, and ensure your PC's virus protection is up to date.
I'll wait for your reply,
