Leading vendors maintain tens of millions of mainland IPs and refresh each call so no single address ever trips Taobao’s behavioural heuristics. A smart request-splitting layer keeps pagination depth and concurrency below the platform’s hidden thresholds. Because many high-value endpoints sit behind the Taobao mobile app, traffic is tunnelled through full Android or iOS emulation with realistic TLS and JA3 fingerprints, making every packet indistinguishable from a real handset. Premium routes also steer around congested Great-Firewall nodes, holding cross-border time-to-first-byte under four hundred milliseconds.
