The Vinted Arbitrage War: Building a Scraper That Doesn't Get IP-Banned

The author documents their failed attempts to build a Vinted scraper for cross-border arbitrage, detailing how datacenter IPs get instantly blacklisted, TLS/JA3 fingerprinting detects non-browser clients, and behavioral analysis flags bot patterns. Vinted operates across 19 European markets with geo-based routing that restricts data access by IP location, making consistent multi-market scraping extremely difficult without residential proxies matched to each country.
