Content sharing services have become immensel popular on the Web. More than 1 billion people use this kind o services to communicate with friends and exchange all sorts o information. In this new context, privacy guarantees are essential guarantees about the potential release of data to unintended recipients and the use of user data by the service provider Although the general public is concerned about privacy question related to unintended audiences, data usage by service provider is still misunderstood. In order to further explore this level o misunderstanding, this work presents the results of a surve: conducted among 900 people with the aim of discovering hov people care about the use of their personal data by servic providers in terms of social media. From the results, we found that: (i) in general people do not read license terms and do no know very much about service policies, and when presented with these policies people do not agree with them; (ii) a good number of people would support alternative models such as paying for privacy or selling their personal data; and (iii) there are some differences between generations in relation to how they care about their data.
