Fighting Fraud

Protecting your recruitment from fraudulent activity is essential to maintain data integrity. Panelfox offers several features to help identify and prevent fraudulent behavior:

Duplicate IP Protection

Panelfox flags respondents who complete surveys from the same IP address in a Study. When duplicate IPs are detected, an alert appears in the Study Overview page.

Restricting by Country

If you observe fraudulent activity originating from specific countries, you can restrict access to your panel and studies based on geographic location. This measure helps prevent unwanted sign-ups from certain regions.

Bulk Blocklisting

Panelfox allows you to blocklist multiple users simultaneously. By compiling a list of known fraudulent individuals or domains, you can prevent them from participating in your studies. Here's how to do bulk actions in a panel.

Implementing CAPTCHA

Adding a CAPTCHA to your screeners and panel sign-up forms can deter automated bots and reduce fraudulent submissions. This step ensures that respondents are genuine and not automated scripts attempting to access your study.

Video Question Type

Incorporating video responses in your screener can help verify respondent authenticity. Requiring participants to submit video answers makes it more challenging for fraudulent users to complete the screener, thereby enhancing the quality of your data.


By utilizing these features, you can effectively mitigate fraudulent activities and maintain the integrity of your research data.
