K-pop under scrutiny after "idol" Sulli died

K-pop actress-singer Sulli rose to prominence as a member of girl band f(x), but she came to be known for speaking out on mental health issues, cyberbullying and women's rights - issues that remain sensitive in a conservative society like South Korea, BBC reports. Guardian goes a step further - London paper reports about anger over the failure of management agencies to protect their stars (in Korea they're called "idols") from the menace of “toxic fandom”.
