• No GREASE values — real Chrome/Firefox/Edge always inject GREASE; their absence is a strong bot signal
• No HTTP/2 (h2) in ALPN — modern browsers always offer h2; most scraping libraries don't

Now test your actual scraper

Run this from your scraping code and compare — a real browser shows GREASE + 15+ extensions; requests/curl won't.

curl https://check.jibaoproxy.com/

# Python
import requests
print(requests.get("https://check.jibaoproxy.com/").json())
