Feature/Custom Solution Inquiry: Implementing Secondary CAPTCHA Challenge

I hope this message finds you well. We have been using CleanTalk on our WordPress site and have generally been pleased with its performance. However, we have encountered an issue with false positives, particularly concerning email submissions that are flagged as fake. This has notably affected traffic from our Google Ads campaigns, leading to legitimate users being blocked from submitting forms on our website.

We have reported these instances as not spam, but we are concerned about the potential loss of legitimate leads. To mitigate this, we are interested in exploring whether it is possible to implement a feature or custom solution within the CleanTalk plugin that would allow for a secondary verification step—such as an aggressive CAPTCHA or another robot challenge—if an initial submission is denied by CleanTalk.

Specifically, we are wondering if there is a way to:

1. Automatically prompt users with a CAPTCHA challenge after their form submission is flagged as spam by CleanTalk.

2. Allow users who successfully complete the CAPTCHA challenge to have their submission accepted, overriding the initial denial.

If this functionality is not currently available, we would greatly appreciate it if you could consider it as a feature request. Alternatively, if a custom solution could be developed to achieve this behavior, we would be interested in learning more about that possibility as well, which would require some illumination from yourselves on what client- and server-side APIs we would need to hook into and work with.
