Althoug I have set a custom volume, people can get an unlimited number of blocks when they set one of the cuboid's sides to 1.
This way they would be able to protect absolutly gigantic cubes with only 6 protection stones. I do not ever want to promote cubes in my theme based server so I would love to see this fixed before more people find out.

Maybe I have set something wrong in my config so I copied it to pastebin.
