In 2017, Mr. Woo revealed that the entrance exam company he belonged to, Etoos Education (Etoos), hired comment workers to write posts that disparaged competing academies or instructors and manipulated search rankings as part of their marketing. He exposed the comment manipulation practices in the entrance exam academy industry and formed the 'Clean Online Lecture Council' with other instructors opposing such manipulation.


Following Mr. Woo's revelations, investigative agencies launched an investigation, and in 2021, the Supreme Court sentenced Etoos CEO Kim Hyung-joong, who was charged with obstruction of business and violation of the Information and Communications Network Act (defamation), to 1 year and 6 months in prison with a 2-year probation. Jung, the head of Etoos's online business division, who was also tried alongside Kim, received a confirmed prison sentence of 1 year and 6 months.



Meanwhile, Mr. Woo's funeral was held at Severance Hospital Sinchon Funeral Hall, Room 17. The funeral procession was scheduled for midnight on the 15th.
