I lost 50 ad accounts before realizing this technical flaw.
A few months ago, we were burning through accounts daily. We thought our creatives were the problem, but it was our proxies. Datacenter IPs have a 96.8% detection rate by modern anti-fraud systems. We finally tested P2P networks and integrated GonzoProxy into our antidetect browsers. Because they use real devices from ISPs like Comcast and AT&T, our accounts suddenly survived the initial sandbox phase. If you're struggling with bans, you need to audit your proxy connection type immediately. No KYC.
