Short answer

Before logging into any revenue-generating store, run a 60-second pre-flight check across four endpoints: IPQualityScore (fraud score under 15), BrowserLeaks WebRTC (zero local LAN leak), Whoer.net (100% timezone and DNS match), and Pixelscan (consistent hardware fingerprint). Fix any failure before you log in.

David Lewin From the field

"Pilots don't take off without a pre-flight checklist. When you're managing seller accounts holding tens of thousands of dollars, taking 60 seconds to verify your proxy tunnel before logging in is the best insurance policy in the world."

The 60-Second Pre-Flight Routine

  1. IPQualityScore / Scamalytics Check: Verify your proxy IP scores below 15/100 and displays ISP / Residential rather than Hosting / Datacenter. Static ISP IPs from Bright Data and SOAX consistently pass with 0–5 risk scores.
  2. Pixelscan.net Consistency Check: Open pixelscan.net inside your AdsPower or Multilogin profile. Confirm it displays 'Consistent Fingerprint — No Automated Masking Detected'.
  3. WebRTC & DNS Leak Verification: Confirm your DNS resolvers belong to the same geographic region as your exit IP.
Pro tip

Lock your profile's OS version and hardware parameters permanently upon creation. Changing a profile's GPU or screen resolution mid-life looks suspicious to anti-fraud systems.

Agency multi-account security: how to manage 50+ client ad and seller accounts without shared logins or cross-client risk

Use each platform's delegation tools first: Meta Business Manager partner access, Google Ads manager accounts, Shopify collaborator accounts and Amazon user permissions. Give every staff member their own login with least-privilege roles, isolate each client's sessions in a separate browser profile, use known static IPs, and offboard access the same day someone leaves.

Browser Fingerprinting 101: How anti-fraud engines track you even in Incognito mode

Browser fingerprinting identifies a device from attributes it exposes to every website: user agent, screen, timezone, fonts, canvas and WebGL rendering, audio processing, and network signals such as TLS handshakes. Incognito mode clears cookies but changes none of these, so the same device stays recognisable across sessions and accounts.
