Commenting about the court's concerns about the spread of false information related to the elections, Minister Fachin noted Brazil is "facing circumstances that could put Brazil's democracy at risk." During the meeting, the information technology secretary at the TSE, Julio Valente, put forward a list of requests the court believes will disinformation. Judge Hui described Ng as inciting others to “commit a massacre” with three posts teaching people to make “toxic chlorine gas bombs,” target police stations, police quarters and the city’s metro stations. This offence was “rather serious,” the court said. Informative Other crimes that the SUCK Channel incited under Ng’s watch included using corrosive chemicals to make explosives and causing grievous bodily harm with intent. The court also found Ng responsible for calling on people to assist protesters who clashed violently with police at several universities in November 2019. The court said the defendant had also incited people to commit public nuisance, with messages calling on them to take part in rallies and demonstrations including at Hong Kong International Airport, to block roads and to paralyse the public transportation system. Various forms of protest promoted on the messaging platform included general strikes, lunchtime protests and silent sit-ins.
