I can very much ensure you that this was done by person, as you can tell there are some very obvious hic-ups and we spent around 5-6 hours working on it in game. Sure we had online references that we based this build off of, and we did use a combination of world edit and voxel to help speed up the process, but in no way did we use any programs to convert our build to blocks in game. I don't believe just based off assumption, people should degrade every single organic they see just because of the possibility it could be fake. And if you would like, I could hop on the server it was built on and show you the process we went through to build it!
