The Twitter account for pop star Justin Bieber was hacked earlier this week.

"Whoever did it decided to question his follower count and insult him with a popularly-used phrase amongst those who dislike him," writes ZDNet's Emil Protalinski.

"Furthermore, the hacker also started unfollowing some of the Twitter users who Bieber follows (we’re talking over 100,000 people here) and then blocking them," Protalinski writes. "Bieber’s team reportedly worked quickly to follow everyone back once they regained complete control of the account."
