Please start a private conversation with me, give me the server information, rough coordinates and a detailed list of things that were stolen or griefed. I'll see what I can turn up.
Also, since the mods will not spawn in items for you, consult this thread for help. http://empireminecraft.com/threads/have-you-gotten-griefed-need-help-click-here.21170/#post-388016
Raging about it won't help. Luckily the EMC mods will track down your griefers for you, sadly they will not give you the items back. Do as Marg said here: And go to the link listed here: If your base was close to spawn (under 5k blocks away), I suggest you move it. One nether block is 100 overworld blocks, so if you need/want to move further away just bring some obsidian, flint & steel, and dig a tunnel for about 2 minutes, and build a portal. You'll be in a perfect location as long as you HIDE THE NETHER TUNNEL. I am welcome to help with this if need be
