Marketplace Scraping in 2026: Why Timer-Based IP Rotation Undermines Parsers
Analysis of one full day of telemetry from MobileProxy.Space reveals how marketplace anti-fraud systems detect scrapers through session continuity and rotation patterns rather than IP reputation alone. Over 2 million IP changes were recorded across 8,878 modems, with a median of 95 unique addresses per modem. Timer-driven rotations accounted for 60.2% of all changes, and 92.2% of those intervals were exact multiples of one minute, with a median of 120 seconds. Such rigid periodicity stands out against natural mobile network behavior where address changes occur irregularly due to cell handovers or PDP context resets. The data also shows that 73.1% of address changes complete within five seconds, yet duplicate rotation commands still occur in 0.8% of link-triggered events. The recommended approach ties rotation to parser session state, recreates cookies and TLS profiles on each change, and waits for address confirmation before resuming requests.
