Crawler Illegal Cases in China is a legal reference resource that documents enforcement actions and regulations affecting web crawler developers in mainland China.
The project addresses the need for crawler developers and data industry professionals to understand Chinese law and compliance requirements. It compiles news reports, legal materials, and regulations related to prosecutions and violations involving crawler development. The resource organizes cases into five categories of prohibited activities: providing crawler services to illegal organizations, scraping and selling personal privacy data, profiting from copyrighted commercial data without authorization, causing website outages through crawler requests, and other violations. Each category includes specific documented cases with links to news coverage and legal judgments, alongside relevant criminal code provisions explaining potential penalties.
Developers working in mainland China who use web scraping techniques should review this resource to understand the legal boundaries of their work. The project is particularly relevant for those building data collection systems, as it demonstrates that liability extends beyond individual developers to their direct supervisors and organizations. The cases show that enforcement has targeted verification code breaking services, resume data aggregation, e-commerce data scraping, novel content distribution, and infrastructure disruption. Anyone considering crawler development in this jurisdiction needs to understand that Chinese law treats certain data collection activities as criminal offenses with sentences ranging from detention to multi-year imprisonment.
The project maintains a curated collection of documented cases with links to original news sources and court judgments, providing primary evidence of enforcement patterns rather than theoretical legal analysis. Updates appear to occur as new cases are prosecuted and judgments become publicly available, with the maintainer noting when cases lack final judgments and indicating plans to update once decisions are published.
