Web scrapers get banned. That's not a bug in your code — it's an intended feature of the sites you're scraping. Rate limiting, IP reputation checks, and behavioral fingerprinting are all designed to block automated access. Proxy rotation is the primary countermeasure. This guide covers everything: proxy types, rotation strategies, working Python code, and the honest trade-off between rolling your own rotation vs paying for a managed scraping API.
