He then programmed the accounts to "follow" the Twitter account of rapper Dave Murrell, who calls himself Fyrare and pays Mr. Vidmar to boost his standing on the social network. Mr. Vidmar's fake accounts also rebroadcast Mr. Murrell's tweets, amplifying his Twitter voice.
Mr. Murrell says he sometimes buys Twitter ads to raise his profile, "but you'll get more with Jim." He says many Twitter users try to make their followings look bigger than they are. "If you're not padding your numbers, you're not doing it right," he says. "It's part of the game."
Mr. Vidmar offers a window into the shadowy world of false accounts and computerized robots on Twitter, one of the world's largest social networks. Surrounded by a dozen computers at his home overlooking a golf course near the Las Vegas Strip, Mr. Vidmar has been buying fake accounts and unleashing them on Twitter for six years.
Today, he says he manages 10,000 robots for roughly 50 clients, who pay Mr. Vidmar to make them appear more popular and influential.
His are among millions of fake accounts on Twitter. Mr. Vidmar and other owners manage them to simulate Twitter users: they tweet; retweet, or forward, other tweets; send and reply to messages; and follow and unfollow other Twitter accounts, among other actions.
Some entertainers pay for fake followers. But false accounts can be political tools as well. In 2011, thousands of fake accounts disrupted anti-Kremlin protesters on Twitter.

This will and should undermine trust." Read more >>
