Facebook's reported user numbers appear to be off by a country mile. Multiple user accounts seem to be chronic. Moreover, besides run-of-the-mill fakes and duplicates, Facebook's identity-theft-enabling business model is, in my opinion, a disgrace for any U.S. public company.
No matter how you look at it, at the time of its IPO, Facebook either underreported the fraud problem, or the fraud growth soared. When was Facebook first invaded by this "new" herd of the walking dead? If Facebook didn't underreport, then why is fraud soaring?
