I have made a file up and I have 100% copyright to it (as I made it). No one has any permission to view/download/copy/reproduce or anything the file except me (and there is only one of me)
The file is at http://www.nzdsl.co.nz/copyright.txt . Do NOT download or view it or anything the file. I'm just file sharing the location of it so I don't forget the location but no one else is allowed to see it.
Now lets see how many automated systems download the file or humans try and view MY file.
