Facebook Developers Now Able to Restrict Aps Based on Age and Location

Facebook has announced modifications to its developer application programming interface so that the creators of third-party applications can restrict their reach by demographic--more specifically, by age or location. The update is designed to help developers who may run into legal issues if they make their applications available to all Facebook users, regardless of how old they are or what countries they live in. This could apply, for example, to promotional applications created by liquor companies that need to restrict access to those over 21 in the United States, or to game makers that have only been licensed in certain countries. We've seen this already with the two versions of board game Scrabble on Facebook: one created on behalf of Hasbro, which licenses the game in the U.S. and Canada, and one by Mattel, which publishes it overseas. The new demographic restrictions in the API use Facebook profile data to determine age and location, and profile data is not always totally accurate. As a result, the social network recommends that developers also ask up-front about those details.
