Dixon's group has found companies selling data on rape victims, seniors suffering from dementia and people diagnosed with HIV and AIDS. She said companies created powerful data sets by combining personal information available from public records, census information and social media."All of us are on these lists, and right now we don't even have the right to find out what list we're on or what they say about us," Dixon said. "And I think it's becoming increasingly important for us to see this information and have some rights so we can get off these lists. For this father and mother, I can't think of a worse thing."
