proxies being detected by synthient

I want to ask how all my residential proxies are being detected. i tried "Unknown Proxies" at $8/gb but im still being detected by synthient.

ip fraud scores below:

look at this https://synthient.com/context/138.121.40.109 it says "RESIDENTIAL_PROXY"

is there any provider that's undetected? please suggest a nondetected residential proxy with country targeting.

same issue their ISP ranges seem flagged
i tried oxy but that didnt work either.

i am still struggling with this issue. are there undetected proxies?

If Synthient is labeling your IPs as RESIDENTIAL_PROXY with high fraud scores, it’s because those ranges are already fingerprinted/flagged in threat intel feeds — there’s no magic provider that’s “undetected forever.” Most residential proxies get tagged fast unless they’re from genuinely fresh, low‑abuse consumer pools and kept stable, otherwise services like Synthient will spot them regardless of vendor branding.
