Now also consider that Paypal imposes a $500 dollar fine on any site site breaking it's mature audience TOS. This fine was established on 8/23/04 and went into effect 9/23/04. So Renderosity may not be suffering from greed. They may need to protect themselves and thier merchant by taking these steps. It might seem exteme, but given Paypal's track record with freezing accounts and the merchants needing that money, I'd say it's probably wise.
