Actually Most toxic stans come from SM due to SM promoting parasocial behaviour. They are too toxic towards other groups as well as their own groups. The only reason many other groups did not take notice because in later 3rd gen BTS and Blackpink completely overtook Exo and Red Velvet. They started gaining on other fandoms in later 4th gen with Aespa and The problem was there with NCT’s fandom being toxic but due to group being too large it did not come to surface. But now it is becoming relevent again with MYs.
