Well i have seen that lockette works for chests but the mods don't always need to break down on the griefers. Also it happens so much on creative if it happens on survival, it could possibly not be seen. I still agree the mods do a great job on banning, but give em a break. They have life's too. They too have things to do and they want some peace sometimes. So i have found something very useful. Here is my idea....
On some servers Ive seen Residences. They protect peoples building from griefing and no one will need to worry about it.
I don't know if we can't have the mod, but it will help a lot. Here is how it works....
Get A Wooden Axe
Create 2 points where you want them(Or pillars 2 blocks tall)
Right Click the top of the first Pillar
Left Click the bottom of the second Pillar
type /res select vert
then type /res create <Res Name> This can be any name you want :>
Then your Done!
Also, I think it requires the Iconomy plugin but it's worth it! It stops Griefing for good!
Hope this helps. :3 -VVX1000
