Justin Bieber’s Twitter account was hacked and an unauthorised message was sent to his 19 million fans. Fortunately the message was quickly deleted and the hacker didn’t do any serious damage at all. According to reports the hacker also began to unfollow and block some of the singer’s followers. It appears that the account was compromised more to spread embarrassing graffiti rather than with more malicious intention. The hacker also reportedly unfollowed and blocked some of Bieber’s followers in the wake of the hack.”]
