An official from the advertising industry said that there had been frequent disputes between the entertainment agency and advertiser because of the damage caused by social insults of celebrities. In 1980, aspects about celebrities' serious crimes, such as drugs, adultery, assault, fraud, smuggling, etc., were added to the terms of advertising contracts.
In the 2010s, gambling, driving under the influence, sexual harassment, and military service avoidance were included in the contract. According to the official, controversies about drinking, smoking, and bullying during school days are being discussed.
