You don't have to name any names
One of the most disgusting ones was when a minor male group member had to be on a hiatus for a long time due to health and somebody was trying to spread the rumors that he got hurt while selling himself to male sponsors. Disgusting thing to make up about a kid!
Also, when Chinese fans were making things up about an idol that committed. They spread that the person was alive in the hospital waiting for their members to alive and that they're hanging on by a thread so we all must pray for them to alive quickly because the idol will surely get better once they're there.
The idol passed away by that point and those were lies. They claimed they had a source in the hospital. I cried for hours after reading those disgusting things because I was so upset. My friend also committed early that month so it hit me hard + I really love that idol and thought they were a kind person. People are messed up.
