The decision to file a complaint was prompted by concern over their younger sisters using the site, said Finkelstein. "If we were having trouble navigating through the privacy settings and privacy concerns, you can imagine what it would be like for someone 15 years old," he said.

As senior law students, entrepreneurs and "techies by nature," Finkelstein and Jordan felt there wasn't enough transparency in the settings. "Whereas Facebook called these privacy settings, these were actually publicity settings," he said.

Almost immediately after filing the complaint, Facebook began implementing changes. A major success was the changes made to the default settings, said Finkelstein. "If a user wants to make their profile more public, he or she can do so, but by no means is it completely public at the onset," he said.
