the biggest one i see: treating the proxy as the whole solution. people buy premium residential, point a raw python-requests/axios script through it, and still get blocked — because the IP was never the only signal. the request fingerprint (tls/ja3, header order) screams "not a browser" regardless of how clean the IP is, and machine-perfect timing scores badly on its own. second biggest: rotating on every request when the target wants session stickiness, so you never build any trust and trip more challenges, not fewer. clean IP first, but a browser-realistic fingerprint and human-ish pacing matter just as much.
