With increasingly large friend networks, Facebook users may be losing sight of exactly with whom they are sharing content they post to Facebook. When Facebook released a new privacy interface in sum- mer 2010 they simplified privacy controls; however, group-based permis- sions remain at the core of fine-grained privacy control. In order to use these fine-grained controls, users must be able to accurately and usefully specify friend groups. In a series of 46 semi-structured interviews, we investigated how participants group their online friends using four differ- ent grouping methods. Our results show that these different mechanisms alter the strategies and groups that users create, that groups created a priori need further refinement before they can adequately address pri- vacy decisions, and that users are adapting their online behavior to avoid the need to specify groups in the current Facebook interface. We con- clude with several recommendations that would allow users improved group-based access control.
