They are still fucking you over, most times people do it on purpose, they'll Derive from you, hide it in their catalog, Derive from that one, and set the end product as Derivable, they'll jack the price up on the second time they derived it from themselves, then when someone goes to buy it or derive it, they have to pay a shit ton for something you only got 100cr for, and if they do derive it then that person gets a shit ton of cr for something YOU did, and if he does it all the time to you, then....he might be doing it repeatedly and as everyone sees how great YOUR products are in his catalog, they keep going to his catalog to buy, and then it's like your getting nothing for your efforts....except 100cr or 1cr etc...
And as I once asked in the IMVU Forums, is it Legit to do that and not get banned, I got a great big YES.
As you set it derivable IMVU won't do shit if someone derives it and only changes it slightly.
