Paul, you don't know me, but I have heard and read about you, and with all due respect I think you're overreacting. I've worked with Nathanael a long time ago at the first few Lego World expositions in Zwolle (NL), so I know a bit about the time and dedication it takes to create models like you do. But if you inspire others with great creations, people will mimic them, and there's nothing you can do about that. If they are willing to pay a few bucks to acquire the instructions to re-create your creations to the stud, more power to them. But charging for moc instructions should not be a given, and putting copyright next to a moc is cute, but ultimately futile.
