For whomever can't read that horrible wording,
He's basically suggesting, like Giovan said, like in CityRP. A bit different, though. If someone builds over your build (ex. making a bunch of 1x1s and plates going over your build [trolling]), you automatically have full trust priveliges for those bricks, so you can delete them, wrench them, whatever.
I actually think this would be pretty cool, but there should be a height limit, too, so if someone happens to build over your build on top of a giant mountain, you wont get trust for those bricks.
