There are good lists of breaches but few describing what happened to the people afterwards. Credit card theft resulting in a loss being the most obvious one.
Such concrete (real) examples would help me to argue with people who say: all this non-sense about data privacy. What would anyone want to do with your data anyways?
This seems more like a security than a privacy issue. The data (credit card info) is not shared intentionally, but is leaked due to a security hole.
