Baidu is facing an investigation into overnight gambling promotions. Regulators in China are looking into the search engine company, after online gambling sites allegedly registered corporate accounts with Baidu, acting under the names of real companies that did not hold accounts with it. The sites would then post ads that appeared only at night on the search engine's pages. The Cyber Administration of China announced that it would publish the finding of its investigation “in due course”, whilst Baidu said that it had reported the latest case to police themselves. Gu Guodong, executive marketing director of Baidu, also said that “Baidu's anti-cheating system still has deficiencies”, but that it would be combatting these issues immediately. This is now the second ad scandal the company has faced this year, after it faced controversy surrounding its medical advertisements.
