I had this happen, but it created an ethical and legal problem which I had to solve. I ran a site taking mortgage leads from websites and auctioning them off to brokers. The bulk of the site was the dashboard for brokers buying leads. You had to be a real (legal) broker and to see the whole system you had to bid on and buy leads of real people. One of my competitors managed to get a real broker ID and get registered and bid on some leads and bought some. They didn't call the customers, but that alone made our system look bad as it is presumed the customer wanted to talk to a broker. I actually called the competitor up and got hold of the tech guy who had made the account. We had a good conversation and I suggested we exchange dummy accounts so we could see inside each other's systems, in the spirit of friendly competition. He agreed, and from then on we could see inside each other's sites and bid and buy fake leads. (Disclaimer: I was already seeing inside their system as I had a broker friend near the office who would let me go to his office and watch over his shoulder as he used their system.)
