Hi there Superstarbot100. First thing I'd like you to do is drop the attitude because it's not gonna help you at all here. I'm not going to 'unban [you] and let [you] see what "[you]" did' because that kind of defeats the purpose of banning someone. I will, however, show you the screenshots I took of the damage.
http://imgur.com/5Qj33P7,hQGLkFl,jgrKLtp#0The first image is the damage after I had undone what you did. Granted, there was further damage inside and from what you'd dug under to get into it. The slime actually turned out to be a giant creeper head that someone had built with a sign that read "creepers gonna creep" on it. The text in chat shows that xboy2002 broke the lime wool, but that was the back; I fixed more damage you'd done in the front.
The second image is the damage before I undid it. (there was more which wasn't shown in the picture)
And the third image is the tunnel you dug under the hole to get into the creeper head in the first place.
Seeing as how you have so many previous bans (two others for grief, one for spamming) tell me why I should even consider pardoning you.
