Obama has millions of fake Twitter followers

President Obama's Twitter account has 18.8 million followers -- but more than half of them really don't exist, according to reports.

A new Web tool has determined that 70% of Obama's crowd includes "fake followers," The New York Times reports in a story about how Twitter followers can be purchased.

"The practice has become so widespread that StatusPeople, a social media management company in London, released a Web tool last month called the Fake Follower Check that it says can ascertain how many fake followers you and your friends have," the Times reports.

Notes the Times:

If accurate, the number of fake followers out there is surprising. According to the StatusPeople tool, 71 percent of Lady Gaga's nearly 29 million followers are "fake" or "inactive." So are 70 percent of President Obama's nearly 19 million followers.
