I am pretty sure that there are no "Build inspectors" that go around investigating every bit of detail on what ever build you make. This is tree is put simply a object, there are probably thousands of ways you can make a tree and yet you could copy somebody's object and put it in you're build if you wanted to. I am 100% sure you do not know what stealing is. If I went onto Bones4's titanic server and saved the build then hosted my own server (which I wouldn't do because I don't steal) named "Mousedroidz21's titanic" then I am stealing the build and claiming that it is mine how ever that is a build which is a huge difference than a object.Technically nearly all builds are probably stealing from someone, the default bricks who are they made by? Badspot or someone I don't know probably Badspot, if I made a build out of default bricks and don't credit Badspot because he made the bricks for the game then technically I am stealing but no one cares because Badspot gave us permission after we brought his game. This is a object a tree, if summet gave you credit then there would be nothing to worry about.
Instead of going insane and flipping tables you could have been civilized and said "Hey that's my tree, glad to see you're using it. If you want evidence its mine then here [insert URL]. Remember to credit me!"
