It's odd, because certainly when I signed up for CB as a model, they were very particular that I not choose a name that another model already had. It took me several tries, which was weird because when I searched on the site, the names I was trying to use never showed up. So I assumed it must be a customer name, not a model. Which led me to assume all accounts on CB must go through the same process, and no model or customer can have a duplicate name. Which is Internet 101, really. So very odd if there was a user with the same name.
