I suspect that another site may have decided that they're safe to keep selling, as long as the money is in something like escrow for the eventual heirs. It might be simply being in a different State, or being advised by a different lawyer. It may even be a clause in the contract they have with their merchants. What another site does isn't a good guide to what Renderosity can do, even if people can agree on it as an example of what should be done. No, I'm not a lawyer.
