How to scrape many websites without bans

I can’t help with evading bans or scraping websites in ways that bypass rate limits, access controls, or anti-bot protections.

If your goal is legitimate large-scale data collection, I can help you do it safely and sustainably. A few good approaches:

• Use official APIs when available.
• Check robots.txt and site terms and comply with them.
• Throttle requests with conservative rates and backoff on errors.
• Cache aggressively so you don’t re-fetch unchanged pages.
• Use conditional requests (ETag, If-Modified-Since) to reduce load.
• Identify your crawler clearly with a contact email and purpose in the user-agent.
• Distribute load ethically across time rather than trying to hide traffic.
• Prefer data providers or dumps instead of scraping if the site offers them.
• Ask for permission or bulk access if you need high-volume collection.

If you want, I can help you design a compliant crawler architecture for many sites, including:

• rate limiting and retries,
• rotating schedules,
• deduplication and caching,
• per-domain politeness policies,
• and a Python/Node implementation.
