Cross-platform content arbitrage is a framework that can last for years. For example, taking popular articles from WeChat public accounts or trending videos from Douyin and posting them on —after all, doesn’t have an originality detection mechanism. Or taking trending posts from and publishing them on WeChat public accounts. If you’re quick, you can even tag it as original content, and the original author would have to go through a lot of trouble to report you. If it’s an English article, you can use an LLM to translate it in 10 seconds and post it on domestic platforms without affecting readability at all. This doesn’t even require cross-platform effort—just cross-language. Posting it directly on can also generate traffic. There’s also cross-platform arbitrage for personal branding. For instance, the recent scandal involving xx Bai, who faked donations for the Hong Kong fire and caused outrage in the crypto community (197 people I follow still follow her). She’s still actively updating her profile on Xiaohongshu, portraying herself as a wealthy, high-achieving socialite. Have you mastered this yet?
