Corollary: Even if you take every reasonable legal precaution, there's still a possibility that you can be held liable once the class action lawsuit is filed.
Yes, but who would pay if you won? The corporation's assets have been stolen, and presumably there aren't enough left over to cover the shortfall (hence the closure of the site). Moreover, unless they screwed up their corporate formalities, the individual shareholders should be protected from this type of loss. Limited liability is one of the main reasons why corporations exist in the first place.
