Since ticket sales opened on Sept. 23 for the Mid‑Autumn and National Day
holidays, China Railway’s 12306 platform has used big‑data and risk‑control
technology to detect and curb malicious ticket‑grabbing. It targets registered
accounts buying on behalf of others, payment accounts repeatedly repeatedly
settling non‑owner orders, and terminal‑device spoofing that mimics user
operations. Technical measures place suspicious 12306 accounts into a slow queue
and refuse ticket issuance for flagged payment accounts; affected users see
waiting prompts during booking or purchase‑failure at payment. Since sales
began, 12306 has placed 7.117 million transactions into slow queues, refused
ticketing for 1.023 million transactions and blocked issuance of 1.331 million
tickets.
