Direct Answer: A Chrome API stub is a partial or placeholder browser capability that automated browsers sometimes expose. BotRefund checks for these mismatches as one of 106 independent signals. A real browsing session normally shows complete, internally consistent browser capabilities, so a stub can...

Direct Answer: A DNS Challenge Blocked check looks for a mismatch between network facts that a real browsing session does not normally create. It is one of 106 independent checks BotRefund uses to build a picture of whether a visit is human or automated....

Direct Answer: A forensic click log contains detailed session records including GCLID and FBCLID identifiers. These logs provide evidence that invalid traffic occurred and can be submitted to ad platforms to claim refunds. BotRefund generates compliance-ready forensic logs you can download for this purpose.

Direct Answer: A free bot audit from BotRefund scans your site for 106 independent signals, including rapid tab blurs, to detect automated traffic. You get a report showing how many bot visits occurred and which behaviors were detected. This helps you decide whether to...

Direct Answer: A Navigation Timing Stub is a placeholder or incomplete implementation of browser navigation timing APIs that some automated browsers expose. BotRefund checks for this as one of 106 independent signals to see if a browser is hiding its real behavior. A normal...

Direct Answer: It is one of the independent checks BotRefund uses to spot automated visits. It looks for a mismatch that a real browsing session would not normally create. Scripts can send clicks and scrolls, but they struggle to reproduce the varied timing, movement,...

Direct Answer: It is one of 106 independent checks BotRefund uses to spot automated browsers. The check looks for a mismatch that appears when automation tools patch or hide browser APIs. A normal browser runs those APIs as designed, so the mismatch stands out....

Direct Answer: A viewport mismatch happens when a browser's viewport or related API properties do not line up with what a real browsing session should show. Automation tools often patch or hide these APIs, but the changes can break when checked from another angle....

Direct Answer: An Accept-Language Mismatch occurs when the language header sent by a browser does not align with the visitor’s IP‑based location or device settings. Real users typically have consistent language and location data, while bots often spoof or rotate these values. BotRefund flags...

Direct Answer: Anti-stealth traps are checks designed to catch bots that try to mimic human behavior by hiding their automation. BotRefund includes traps that look for patched browser APIs, debugger presence, and other anomalies. These traps are part of the 106 independent checks that...

Direct Answer: Anti-stealth traps are checks designed to catch automated browsers that try to patch or hide their automation flags from basic detection tools. BotRefund includes these as part of its 106 independent checks, targeting mismatches that appear when automation tools try to modify...

Direct Answer: An audio channel mismatch happens when the audio details a browser reports do not line up with the device it claims to be using. Virtual machines and spoofed profiles often create this kind of inconsistency. BotRefund treats it as one of 106...

Direct Answer: Asset starvation is a check that identifies a mismatch in a browser's environment that a normal user would not create. Automated toolkits often leave distinctive shortcuts or remnants that reveal the browser is being controlled. BotRefund uses this as one of 106...

Direct Answer: FlareSolverr Patch is one of the 106 independent checks BotRefund uses to separate human visits from automated ones. It looks for shortcuts or browser remnants that automation toolkits like FlareSolverr leave behind. A normal browser does not usually create this kind of...

Direct Answer: Hardware & GPU Fingerprinting involves examining the hardware and graphics details reported by a user's device. A normal browser reports details that naturally fit together for that device. Mismatches can indicate that a virtual machine or spoofed profile is being used, which...

Direct Answer: Independent evidence means each signal adds one objective fact about the visit. BotRefund does not trust one signal by itself. It cross-checks that fact against other browser, network, device, and behavior data. The AI model then weighs the complete pattern to decide...

Direct Answer: Pixel poisoning happens when bots trigger conversion events on your site, causing your ad platform to optimize for fake signals. This corrupts your lookalike audiences and can spike your CPA. BotRefund prevents this by suppressing the Meta Pixel in real time when...

Direct Answer: Pixel poisoning happens when bot sessions trigger your Meta Pixel conversion events, feeding false signals to the ad algorithm. The algorithm then optimizes toward more bot-like traffic, raising costs while real conversions decline. BotRefund suppresses pixel conversion events during bot sessions in...
