Despite their many talents, achievements, and exhausting hard work, K-pop stars unfortunately attract plenty of haters in the form of anti-fans. However, some anti-fans just go way too hard to stop K-pop stars in their tracks. Here are 10 of the most chilling instances of anti-fans' attacks.

1) Yunho

In what is probablythe most notorious anti-fan incident today, a young female anti-fan ofTVXQhandedYunhoa drink of what he believed was orange juice but actually contained glue. After drinking it, however, he found himself getting violently sick, vomiting afterwards. He was then admitted to the ER, where he remained hospitalized for several days. Rather than pressing charges against the anti-fan, however, he chose to forgive her since the girl was the same age as his younger sister.

2) Yoon Eun Hye

During her days as a member of girl groupBaby V.O.X,Yoon Eun Hyefound herself constantly terrorized by anti-fans. One incident in particular left her physically injured when a man squirted a mixture of vinegar and soy sauce directly into her eye, causing damage to her corneas and forcing her to wear an eye patch during her activities.

3) Girls' Generation

Termed today as the"black ocean" incident,Girls' Generation's anti-fans shut off their glow lights and ceased their cheering during the 'Dream Concert,'forcing the girls to perform in dark silence. The fact that this occurred recently after the girls' debut only made it worse as no one wants to face such ostracism in their rookie days.

4) Jay Park

One would think thatJay Parkwould have enough on his plate right after his departure from2PM. Anti-fans apparently didn't think so, however, as they actually created a petition that called for his suicide. Titled "Jaebum should commit suicide," this petition managed to get over 3,000 signatures before finally getting taken down from the internet.

5) Super Junior

During theDream Concert, the same concert where the "black ocean" incident actually occurred,Super Junior's anti-fans went ahead and tore down all of the stage banners featuring Super Junior. However, this was all done right in front of the members... while they were still performing.

6) Kan Mi Yeon

With great popularity comes great numbers of anti-fans as well. During her days as a member of Baby V.O.X,Kan Mi Yeonwas known to have a strong, huge fanbase. However, her anti-fans grew high in number after it was rumored that she was datingH.O.T'sMoon Hee Jun. One fan sent an envelope with razor blades as well as a letter containing a death threat, prompting her to immediately report the incident to the police.

7) 2PM

Sending flowers can be a nice gesture to show friendship and love for the receiver. However,2PMfans were terrified when anti-fans sent bouquets of flowers that symbolize death in Korea. Luckily for 2PM andHOTTESTs, no physical harm came out of this incident.

8) Song Eun Chae

Formerly known asKang Eun Bi, this actress faced so much hate from anti-fans thatshe attempted suicide at several points. The psychological distress from anti-fans stalking her, harassing her family members, and throwing milk, eggs, and tissues at her proved to be too much for her, causing her to attempt suicide several times.

9) Yoon Kye Sang

During his days ing.o.d,Yoon Kye Sangreceived a drink from an anti-fan. Not knowing that the giver was an anti-fan nor that the drink was poisoned, he handed the drink over to his mother, who fell violently ill after consuming it. She was then rushed to the hospital, where she had to get her stomach pumped.

10) Tablo

It's always great to hear about non-entertainment accomplishments that our favorite K-pop stars have achieved in their lives. However, some anti-fans clearly didn't think so whenTablorevealed that he was an alumnus of the prestigiousStanford University. Anti-fans quickly rallied to create the forumTajinyo, claiming that Tablo had faked getting his diploma from Stanford. They continued to harass him and his family members for two whole years, tarnishing his reputation and causing him much mental stress even afterStanford representatives affirmed his alumnus statusand jail sentences were issued for harassment.
