In need of help!!!

while looking around for a server one day, i found a great one, but since it was cracked, one of the moderators/ administrators removed it. today i asked the owner if i could build a central plaza with creeper face pixel art. i started, and then someone came on, apparently, s/he was a griefer. they killed me and took my wool, and started building swastikas all over the place, also screwing things up in general. without knowing who originally posted the server, i cannot contact the owner and explain. beware of anyone who comes on your server that is named riceman, zullie, or who claims to be from team avolition. in concise terms, what admin removed it, and can they tell me who posted it?
