Online retailers may operate one or more services configured to detect requests generated by automated agents. A CAPTCHA may be transmitted in response to requests generated by automated agents. The CAPTCHAs may be included in a modal pop-up box configured to be displayed by a client application displaying a webpage to a customer of the online retailer. Furthermore, the CAPTCHAs included in the modal pop-up box may be rendered inactive and caused not to be displayed by client application executing the webpage. Rendering the CAPTCHAs inactive may provide an additional signal which may be sued to update one or more automated agent detection models.
