Briefing
- Scrapfly: Scrapfly released a walkthrough covering nine mechanisms that can block a Scrapy spider, from IP reputation to CAPTCHA, with evidence and mitigation steps for each.
Why it matters
This guide consolidates the most common blocking vectors into a single reference, giving practitioners a structured way to debug blocks without jumping between tools. By mapping each mechanism to a cheapest test and a native Scrapy control, it lowers the barrier for teams that need to keep extraction pipelines running. The inclusion of newer signals like TLS/JA3 and HTTP/2 fingerprinting reflects how anti-bot systems have evolved beyond simple rate limits.
