Fraud detection and response quality

Automatic detection of suspicious responses with quality classification.

QuestionPunk automatically classifies each response with a suspicious level (low, medium, high) based on attention checks, response timing, and behavioral signals. This helps you filter out low-quality or fraudulent responses.

Steps

  1. Automatic classification
    Every response is automatically analyzed and assigned a suspicious level: low (likely genuine), medium (some concerns), or high (likely suspicious).
  2. Filter responses
    In the Responses tab, use the filter dropdown to show only low-suspicious responses, or review high-suspicious ones manually.
  3. Review signals
    Each response shows its session details: IP address, location, device info, time spent, and events. Use this to verify response quality.

Fraud detection runs automatically on every response. The system checks response timing, attention check answers, and behavioral patterns.

Suspicious level is included in CSV exports, so you can filter at the analysis stage. Use the Responses tab filters to review flagged responses before exporting.

For studies using panel providers like Prolific, fraud detection helps identify participants who may not be engaging genuinely with your survey.
