Stop Flying Blind: How to Check Proxy IP Fraud Scores in 2026

I see this happen on BHW constantly: a guy buys a fresh batch of residential proxies from a new vendor. He loads them into AdsPower, attaches his high-limit Agency Accounts, fires up the campaigns, and goes to sleep.

He wakes up, and 5 out of his 10 accounts are permanently disabled.

He blames the ad network. He blames the BM provider. He rarely blames the proxies, because "Hey, I paid $15/GB, they must be clean."

Wrong. In 2026, assuming a proxy is clean out of the box is operational suicide. Before that proxy ever touches a Facebook or Google login page, you must manually vet its IP Fraud Score.

What is an IP Fraud Score?

Major tech companies (Meta, Google, Amazon, Stripe) don't maintain their own isolated blacklists anymore. They subscribe to massive third-party security databases like IPQualityScore (IPQS), MaxMind, and Scamalytics.

When you connect to an ad platform, these databases instantly analyze your IP address against millions of data points:

• Has this IP been used for carding or financial fraud recently?
• Is this IP a known Tor exit node or public VPN?
• Has this IP engaged in aggressive web scraping or bot-like behavior?

If the score returns too high (usually anything over a 30 out of 100 on IPQS), the ad network treats you as hostile. You are dead on arrival.

The "Dirty Subnet" Problem

Even premium residential proxy vendors recycle their IPs. The guy who rented that exact IP address yesterday might have used it to spam 10,000 Russian phishing emails.

Worse, sometimes entire subnets (blocks of related IPs) get blacklisted. So even if your specific IP shows clean, if the 20 IPs surrounding it were flagged for fraud, your IP inherits a guilt-by-association penalty.

The Verification Workflow

This should be non-negotiable for every single media buyer reading this.

1. Acquire the Proxy: Set it up in your Anti-Detect browser profile.
2. DO NOT LOG INTO ANY AD NETWORK YET.
3. Run the Tests: Navigate to a site like IPQualityScore or Scamalytics. Enter the proxy IP or just visit the site through the proxy.
4. Analyze the Data:
   • Fraud Score: If it's above 15, throw it away. Request a new IP from your vendor.
   • Proxy/VPN detected: Ensure it says "False." If their basic system detects a proxy, Facebook will detect it instantly.
   • Location spoofing: Ensure the detected location matches what the vendor promised.

Stop Trusting, Start Verifying

The proxy providers listed in the AdAccountsHub directory generally maintain the cleanest IP pools in the game. But nobody is perfect.

Adding a 3-minute IP fraud check to your SOPs will save you tens of thousands of dollars in burned ad accounts and stranded funds. Do the work.
