I apologize, I phrased my question poorly. I'm aware that I can contest their standing in court, but I'm just wondering how it's legal for a JDB to pose as a hospital or physician's group. I've been told over and over that impersonating a creditor is fraud, and it certainly seems like it, but I can't find an actual statute, or even a precedent other than an Amex case that made the news a while back.
