Let's also limit how many commercial models one customer can buy, shall we? No purchase option for new users and 2 purchases per month for old users. This would help with reselling stollen models nicely, right? Wrong. The problem is not in availability of free models, the problem is in people who are breaking the law and selling them illegally. Why should we punish innocent people just because of the criminals? Marketplace should focus on fighting against thieves, not against honest community members.
