Borders Books Customers, Watch For Database Opt-Out Email

An anonymous reader writes "That email you might be getting from Barnes and Noble might not be spam, but rather your only chance to prevent the comprehensive record of your buying history at defunct arch-rival Borders from ending up in B&N's data warehouse. You have15 days after the email arrives, assuming that it ever does, since chances are the email address you originally signed up with Borders is long gone." For that very reason, this sounds like a good place for the terms of the bankruptcy to require opting in, rather than opting out.
