Austria's national Post Office is facing intense criticism for collecting and selling its customers' data. According to the investigative journalism website Addendum, the postal service sold the names, addresses, age and gender of roughly three million customers to other companies for them to use in targeted marketing. Customers' likely political allegiances can also be extrapolated from the data that was provided. Epicenter Works, a privacy campaign group, warns that this practice contravenes EU data protection rules, although postal authorities say the practice is legal under national law.
