The numbers of users reported by Facebook, Twitter, Google, and many other sites, are closely watched. They reveal trends in adoption and they are one of the few public metrics available to analysts trying to assign value to companies preparing an initial public offering.

But how accurate are these numbers?

In some anecdotal cases, the number of users, active and actual, could be as small as one-third. And nearly one-half of user accounts could be fake or contain no user profiles.

No user profiles means very little usable data for marketing or advertising campaigns. This is a huge hole in social media platforms.
