Modern bot detection doesn't just look at what you do; it looks at who you are at the browser, network, and TLS levels. To extract data at scale, you need to harden your scrapers. This guide breaks down a production-ready Python script from the Wayfair.com-scrapers repository that combines undetected_chromedriver with residential proxies to bypass these triggers and maintain high success rates. The Anatomy of a Block: Why Standard Selenium Fails Wayfair's defense mechanisms are multi-layered. When a standard Selenium instance connects to their servers, i
