The irony in this story is so thick I may need a spatula to complete it.Here's a lesson in how not to do business on the Internet: a) Start a company that guarantees your customers never have to worry about having their identity stolen;b) Publish your own Social Security Number on your company's Web site, to show just how foolproof your service is;c) Allow a mentally retarded person to steal your identity, using the SSN you've just broadcast to the world;d) Send thugs to his home to wring a confession from him, making the crime impossible to prosecute.
