angry tapir writes "All those pet cat profiles add up: Facebook has reported that roughly 76 million of the 1.06 billion user accounts on its social network are bogus in some way or other. The company identifies three types of accounts that don't represent actual users: duplicate accounts, misclassified accounts and undesirable accounts.

Facebook disclosed the figures in its annual report filed with the U.S. Securities & Exchange Commission."
