Knowing identity of carlos allows credible legal threat to stop his nonsense. He doesn't care about actually running a coin, so your protection doesn't work. People will still get scammed and then might blame NXT.
If you want to legally prohibit people from redistributing and using your code in other projects, copyright law already does that. Open source doesn't mean anyone can use it if you have a copyright notice on the code.
This no difference between software and images copyright.
Simply add on top of every source file:
/*
* Developer : Developer Name (
example@example.com)
* Date : xx/yy/zzzz
* All code (c)2014 name -- all rights reserved
* You may not use, copy, or distribute the code without written permission from the developer
*
*/
Yeah it's as simple as that.
That makes it illegal to use the code without developer's permission.
