The term may or may not be the same in common law as in germanic legal tradition, anyway...
I'm reacting on two things and since I'm a member of this forum, yes therefore it's partly anyone's business. Why? Because I don't like the idea of gracefully turning up and claiming that you're doing something exclusive for the fans when you're making a large profit.
And second, you're the one making judgement regarding who's the genuine fan. (If a non-genuine fan made you an offer, would you sell? For your sake I'm marking this as a rhetorical question). I truly despise that whole "being genuine" discussion and I was being sarcastic about it. And you kept it rolling with your final argumentum ad populum (which you ended with not only one, nor two, but three exclamation marks!).
If you're gonna make profit, then be open about it, don't disguise it. I find that fully acceptable.
