How do you mitigate fake and bot-based signups and qualify the right ones automatically?

I'm building a tool to do just that. Some CRMs have basic rules you can put on form fields that allow for validation like "must be a number" but they're pretty limited. CAPTCHA is pretty useful for blocking bots too. However, there's not much out there preventing humans from entering fake information. https://www.producthunt.com/prod...
