A man with a strong foreign accent called asking how much would I charge him to provide him with the places of birth of 200 people. He said that he had their names and Social Security numbers and that he thought that I could obtain their birth parents' names, too. I told him that it was illegal for me to give him such information.
This guy managed to use my father's call forwarding feature and hijack his phone calls. He made death threats to me and my father when I tried to call my father. AT&T provided me with his number.
