Big Bang's Seungri spoke up against an impostor on social networking sites.

He tweeted, "I don't use Facebook. That ID is used by an impostor, who acts like he's me and is contacting my fans and acquaintances. Everyone, don't be fooled."

Someone using the ID "OfficialSeungRi" has been duping the idol star's fans and friends into believing that he's actually Seungri himself.

Fans commented, "There are too many hackers and fakers these days," "What is the impostor thinking he'll do with it anyway," and "I feel bad for celebrities."
