Girls' Generation singer Sooyoung threatened an online impersonator last week in a post on the K-Pop group's website SMTOWN.com

"I cannot just stand by watching the rampant impersonations that have been going on," Sooyoung wrote. "Hehe. At first I just tried to laugh it off, but after seeing our SONEs' hearts become troubled by these perpetrators, wouldn't you get mad too?"

The Girls' Generation singer also called out her impersonator directly.

"To the fake Sooyoung: if you are reading this post, please stop now," the real Sooyoung wrote. "Although I am thankful for your wish to communicate with the SONEs temporarily on my behalf, don't do it any longer, hehe. If you don't stop and continue doing this, I will do something about it."

The Girls' Generation singer did not elaborate on what that something would be.

Idle threats to impersonators notwithstanding, Sooyoung's posts have been mostly whimsical positive thank you letters to the fans.

Even in the same post where she threatened her online impersonator, the Girls' Generation star took the time to wish readers a happy spring.

"Everyone, are you doing well?" Sooyoung asked. "It sounds like spring is coming hehe. Should we walk as the flowers fall along the path? hehe I heard Korea is very cold. Don't become careless because spring is coming, and please be careful of catching a cold!!"

On Saturday the K-Pop star also waxed poetic on SMTOWN.com about the coming springtime.

"If you hear the sound of spring coming, walk along the path of petals falling," Sooyoung wrote. "Tokyo's cherry blossom trees came into full bloom! The girls will be going from Tokyo to Hong Kong...HK make some noise!"

In a recent Girls' Generation documentary for the Japanese channel, MBS, Sooyoung said she wanted to to be considered an artist not a pop idol.

"It's hard to differentiate between idols and artists, but I want to be called an artist," Sooyoung said.

Sooyoung's bandmates in Girls' Generation were also asked if they considered their group pop idols or artists.

"To be honest, it's an honor to be called an idol," Jessica said. "The word idol is like that. But recently, the meaning has changed a little bit. Now, if you're young, you're just labeled as an idol. Idols and artists are considered different."

Yuri feels it's up to Girls' Generation's fans to decide.

"I don't think you can differentiate yourself as an idol or an artist," Yuri said. "We're just following people's perceptions."

Hopefully fans can differentiate between Sooyoung and her impersonator.
