Combined from stop order numbers with no info:

Is there any way we can stop orders from coming through with no customer info? I get them often and there should at least be a email address that we can invoice. My listings are set as buy it now and it makes no difference at all. I even had one that had comments from the customer about how nice my stuff is but no info at all and she of course she did not pay.

I think that an order shouldn't be able to be completed without entering payment information and/or contact information - if they choose not to register it with the site, that's fine, they can still be a "guest" and not have an account.
