Then you'll have to deal with people saving your builds then. It's a core feature of the game. This whole topic is as dumb as those javascript crap things that try to stop you from saving images in your browser. People like to save builds so they can look at them locally and play with them later, or maybe add on to them on their own server.
Just because a few 12 year old dorks like to claim credit for other people's work doesn't mean you should cripple the whole game. Just ignore those people.
