Customers will not be informed if they were affected, however, with Facebook instead offering a "help centre page" 

Said page is for users concerned that their data may have been released and outlines that only information that was shared publicly on users' profiles at the time of the scraping has been taken, meaning the data does not include information that was shared only with users' friends.
