A JA3 hash condenses a TLS handshake into a 32-char string. Two different clients can—or intentionally may—generate the same hash, creating a collision. Engineers exploit collisions so automated traffic shares fingerprints with mainstream browsers, lowering detection.
Best practice with Proxied:
- Rotate IPs: Even if your scraper collides with a common JA3, repeated requests from one IP still raise suspicion. Rotating via Proxied's mobile gateway spreads identical fingerprints across many trusted carrier addresses.
- Blend headers: Match User-Agent and language headers to the browser family whose JA3 you're re-using for seamless camouflage.
