Public channels are public to the internet, regardless of whether or not they are subscribed. A public channel is displayed in search results and has a short address (link). Ng Man-ho, a 27-year-old computer technician, was convicted last month of seven counts of incitement charges after he made use of the 100,000-member Chinese-language channel that he runs and manages to post "seditious messages," which had been shut down since August 2020. Those being doxxed include outgoing Chief Executive Carrie Lam Cheng Yuet-ngor, Chung and police assistant commissioner Joe Chan Tung, who heads police's cyber security and technology crime bureau. Hui said the time period and nature of some offences “overlapped” and thus their prison terms could be served concurrently. The judge ordered Ng to be jailed for a total of six years and six months. The public channel had more than 109,000 subscribers, Judge Hui said. Ng had the power to remove or amend the messages in the channel, but he “allowed them to exist.”
