What we tested. Underdog DFS, browser-based Radar geolocation deployment. Installed the free Location Guard Chrome extension and reported a spoofed location.

What happened. Undetected. Radar did not flag the browser-extension spoofing.

Adjacent gaps from the same test (April 28 weekly).

• Device-counting logic flaw — every login at Underdog is recorded as a new device, regardless of whether the device has been seen before. Inflates device counts and prevents multi-account detection — significantly weakening fraud detection.
• Border crossing — testing confirmed users can continue placing wagers for approximately 1 minute after entering a restricted zone before Radar intervenes. Regulatory compliance risk.
• Increased geolocation frequency + buffer-zone false positives — no single-license support; more frequent checks; unnecessary failures.
• Loss of meaningful error messaging — generic error messages for all geolocation failures post-GeoComply switch; ability to self-troubleshoot eliminated; support contact volume likely up.

Why it matters. A free Chrome extension that anyone can install defeating Radar's regulated-DFS deployment is the entry-level sophistication. The device-counting flaw makes multi-accounting effectively free. Bundle these into the Underdog talking points.
