Captchas at every step, registration denials, a shadow ban right after account creation — the cause is often not your actions but a high fraud score of the IP address. Antifraud systems assign each IP a risk rating in advance and use it to decide whether to trust the connection. Let's break down what a fraud score is, which signals it consists of, and which methods actually lower it.
What a fraud score is
Fraud score (risk score, IP reputation) is a numeric estimate of the probability that a connection from a given IP is linked to fraud or automation. The scale is usually 0 to 100: the higher the value, the "dirtier" the address. The score is computed by specialized services and platforms' built-in antifraud modules, aggregating dozens of signals.
- Low score — the IP looks like an ordinary home or mobile user.
- High score — the address resembles a proxy/VPN/data center or has appeared in incidents.
What the risk score consists of
ASN type
The main factor. Hosting ASNs (clouds, data centers) immediately raise the score — a legitimate user almost never goes online from a data center. Residential ASNs are more neutral. Mobile carrier ASNs are the most trusted class thanks to CGNAT and a real mass of subscribers.
Blacklists and history
An IP landing in DNSBLs, spam databases, or known proxy and VPN pools sharply raises the score. Past "dirty" activity from the address is also taken into account.
Proxy/VPN markers
Typical open ports, characteristic headers (X-Forwarded-For, Via), a mismatch between the TCP/TLS fingerprint and the declared OS, a desync between IP geolocation and the client's timezone.
Behavior and density
Many accounts and registrations from one address in a short time, machine-speed actions, abnormal traffic patterns.
Why mobile IPs have a low fraud score
A mobile address is fundamentally different from a hosting one.
- CGNAT. Hundreds to thousands of real subscribers hide behind a single public carrier IP. Systems cannot treat such an address as "one bot" and keep the score low.
- Trusted telecom ASN. This is legitimate consumer traffic, not a data center.
- Pool dynamics. Addresses are reused between subscribers — old "dirt" does not stick to a specific node.
That is why the most effective way to lower a fraud score is to move from a data-center or dubious residential IP to a mobile one.
How to lower a fraud score: in practice
1. Switch the IP class to mobile
The basic and most effective step. turbon.rent mobile proxies run on physical SIM cards of real carriers in GoIP/Simpool gateways: a mobile ASN and CGNAT give a low starting score. 17 countries are available, with IP change on demand via API and SOCKS5.
2. Take a fresh IP before an important operation
Rotation via API yields a new address from the carrier pool right before a registration or login — without accumulated history for that specific session.
3. Close the leaks
Open WebRTC and a DNS leak reveal the real address and break the whole disguise, instantly raising risk. Before launching, run WebRTC and DNS leak tests: only the proxy IP should be visible, with DNS going through the tunnel.
4. Align the environment
IP, timezone, language, and locale must match. A mobile IP from one country with a system timezone from another is a clear anomaly. Set up the antidetect profile to match the proxy's geolocation.
5. Reduce density per address
Do not register dozens of accounts from one IP in a row. One account — one network identity; use rotation for scaling and a stable sticky IP for management.
6. Use clean registration data
A number with a usage history drags along a trail of previous registrations. For verification, take numbers with no history — turbon.rent OTP activations on physical SIMs of real carriers.
What not to do
- Rely on cheap data-center proxies and "fake" behavior — the score stays high because of the ASN.
- Run a long-lived account through constant IP rotation — sharp jumps raise suspicion by themselves.
- Ignore fingerprint: even a perfect IP won't help with duplicate canvas/WebGL across profiles.
Frequently asked questions
Can a specific IP's fraud score be "reset"?
Not directly — the score is computed by the external party. But on a mobile pool you simply take a fresh, low-risk address via API, which is equivalent to a "clean start."
Does a low fraud score guarantee no ban?
No. A low score removes the IP vector, but fingerprint, behavior, and data links remain. It is a necessary but not the only condition.
Why is a data-center IP always "red"?
Because of the ASN: systems know that ordinary users do not go online from data centers, so such traffic is risky by default — regardless of behavior.
Bottom line: a fraud score is determined primarily by ASN type, blacklists, proxy markers, and density. The most reliable way to lower it is to move to a mobile IP plus eliminating leaks and aligning the environment. Connect turbon.rent mobile proxies on physical SIMs in 17 countries with SOCKS5 and rotation via API, and take clean numbers for registration through turbon.rent OTP activations.
