Scraped 300 pages successfully. Site updated robots.txt at page 187 and blocked me. Building a price tracker for electronics. Target: 300 product pages across an ecommerce site. Tested first 20 pages, everything worked. Ran the full scraper overnight. Woke up to find 187 products scraped, then nothing. Zero errors in my logs. What happened The site admin updated their robots.txt while I was sleeping. Added Disallow: /products/* between page 187 and 188. My scraper checks robots.txt once at startup, then runs. By page 188, their server started returning 403 Forbidden. Fun times. The mess I made First attempt: Just scraped the remaining 113 pages ignoring robots.txt. Got IP banned within 15 minutes. Smart. Second attempt: Added 5 second delays between requests. Still banned. Slower this time, but same result. Third attempt: Residential proxies. This worked but cost $40 for what should've been free data. What I changed import requests from urllib.robotparser import RobotFileParser import
