Having read this thread off and on since it was started, not sure it's really going anywhere now, and is probably unfeasible (programming wise) to address.
The problem with illicit/improper/immoral/unauthorised copying of setups is exactly same issue some people have with their original Autocross and track layouts and/or car and helmet skin designs being copied.
In a slightly different way, it could probably be argued that its the same for some InSim overlays (text, graphics, tables, etc), in that an idea can be implemented by someone, another programmer sees it and if they like it, make their own code to do something similar.
The correct answer to setup, layout and skin stealing is a moral one;
just because you know a way to get them, doesn't mean you have to.
In my view, its much better and satisfying to share.
LFS has given me a lot of fun and satisfaction over a lot of years, and part of that satisfaction has been due to a lot of people who have been willing to share things with me, whether that be ideas, advice, sets, layouts, driving tips , programming tips, as well as non LFS things, and also me being able to contribute a small insignificant part to the LFS experience too, whether that be my own sets, layouts and LFSLapper insim programming.
