ONF conducted a virtual comeback performance on August 10, Monday, which was supposed to be without live audiences.

Soon after the performance, WM Entertainment said uninvited "fans" had managed to sneak into the location and breached "the etiquette of fan clubs."

WM Entertainment finally put out a statement on their official fan cafe, exposing what the sasaeng fans did at the gathering, and eventually accepting responsibility for not being able to stop the sasaengs from stirring up trouble.

The statement reads, "We noticed some supporters without authorization coming into the location and stand-by locations. They have also taken recordings of the preparation and the real presentation, which contradicts our rules. They were able to get their hands on classified papers, ate the food reserved for the workers, and the music artists, and after being found hiding in the toilet, they managed to fight with security forces."

"All of that caused difficulty operating a seamless showcase. Specifically, by accessing the stand-by area, they created some nuisance to our artists. The field where performers train for their shows, which has contributed to interruptions in the schedules of our artists." (via Kpopstarz)

The agency concluded their public statement by assuring the fans that they will tighten the security better the next time they will conduct presentations like that and apologized to the public and supporters. Many fans questioned why the firm had to apologize for something they didn't do; instead, others assumed that certain sasaeng fans must publicly admit and apologize for what they had been doing.

It led to a conversation about sasaeng fans - by description. A sasaeng is a fan bordering on obsession, ready and able to go to various lengths and even violate their favorite celebrity's personal rights just to be recognized. Most internet users claim that sasaengs aren't fans of their acts and deserve appropriate punishment.
