In this photo taken Monday, Oct. 10, 2011, Austrian student Max Schrems sits with files about his activities on his Facebook account that Facebook handed over to him, in Vienna, Austria.

Schrems wasn't quite sure what information about himself Facebook would send him after he filed a request with the social networking giant to receive his personal data, as is required under European law. It certainly wasn't the stack of 1,222 pages worth on a CD that inspired him to launch an online campaign aimed at forcing the social media behemoth to abide by European data privacy laws something the Palo Alto, California-based company insists it already does.

Since August, some 350,000 people have visited the site, dubbed "Europe vs. Facebook," and flooded Facebook's European branch, based in Ireland, with requests for their personal data. (AP Photo/Ronald Zak)
