Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use rotating proxies and respectful delays
Using rotating proxies and respectful delays helps evade anti-scraping mechanisms like CAPTCHAs and rate limiting by distributing requests across multiple IPs and mimicking human browsing behavior. Option A is incorrect because using a single IP address makes it easy for the website to block all requests from that IP. Option B is incorrect because disregarding robots.txt may violate the website's terms of service and could lead to legal action or IP bans. Option D is incorrect because increasing request frequency would trigger rate limiting and increase the likelihood of being blocked.
