OGE is a known booster in the Overwatch Community in Korea. Account Boosters are considered to be extremely distasteful as it robs legitimate contenders of securing a professional career. It seems to be something similar as Fissure has expressed his opposition to OGE and his boosting history publicly. He has taken on KyKy, the Dallas Fuel coach as well as trying to express his opinion.
Account Boosting is a very bad precedent and we have had Riot Games also ban a player for 1000 years from the Korean region. Blizzard should hopefully take some similar steps in order to prevent account boosting in Overwatch at the highest levels.
