Ethical Framework

Principles of Ethical Scraping

1. Respect robots.txt and Terms of Service
   - Check robots.txt before scraping any site
   - Review the site's ToS for explicit prohibitions
   - When in doubt, contact the site operator

2. Minimize server impact
   - Use rate limiting (1-2 requests per second maximum)
   - Scrape during off-peak hours when possible
   - Cache responses to avoid redundant requests
   - Use conditional requests (If-Modified-Since headers)
