    Why Your Marketplace Scraper Keeps Getting Blocked (And Why It’s Not a Code Problem)

    This story was originally published on HackerNoon at: https://hackernoon.com/why-your-marketplace-scraper-keeps-getting-blocked-and-why-its-not-a-code-problem. Marketplace anti-bot systems increasingly score network identity instead of scraper logic, making rotating residential proxies essential infrastructure.

If your marketplace scraper keeps hitting 403s and CAPTCHAs, the problem isn't your code: it's your IP identity. Datacenter and static IPs fail anti-bot scoring systems. The fix: rotating residential proxies, geo-targeted to your marketplace's locale, with a rotation model matched to your target's session behavior.

Exporting Apple Health data results in massive, messy XML files that are difficult to process. By using a "streaming" parser to filter specific LOINC codes and extracting GPS kinematics from GPX files, I converted 300MB of raw records into clean CSVs. This structured data is now ready to be fed into a custom machine learning model to reverse-engineer VO2 Max.
