Traditional moderation systems are built to handle abuse, such as threats, stalking, and spamming. Chinese moderation systems are built differently. As the title "Illegal and harmful information" suggests, they're primarily built around suppressing speech that is deemed politically undesirable. If you're interested in the details, I highly recommend you read the article written by someone who worked at 抖音, China's TikTok [1]. Oftentimes Chinese platforms are extremely responsive to reports about political speech, but are sluggish or do not respond at all to reports about abusive behavior. The Chinese systems are just designed differently, and are usually connected or even run directly by the government. e.g., if you click through on Gitee, you end up on a page run by the "Cyberspace Administration of China" [2].
