why do intl kpop fans care so much about k-netziens?

probably this question has already been brought here and I'm on kpop for almost a dacade and I still can not found a valid reason about why there are so many pages who translate their opinions.

Are their inputs so relevant to what international fans think about the groups / idols ???

(I was scrolling on twitter and saw a random account about k-netz translations and there was an article of BoA brother having cancer and some opinons were so emphatically off)

for my experience watching dramas... it seems like there is a bullyng culture on south korea???? we can even notice how many idols were accused of being bullies before debuting... i don't know if there's a relation with the netziens
