A bit more context on why I built this. I've been running a rewards site for years, so I've spent a ridiculous amount of time looking at fraud. The frustrating part isn't that the signals don't exist. It's that most fraud tools are either expensive, designed for much larger companies, or give you a score without really telling you what happened. I wanted something I could actually plug into a small product and understand immediately. So I built Kaidn around a simple idea: Don't give me a mysterious fraud score. Show me the evidence. If someone is signing up from a known Mullvad exit, has already created 4 accounts from the same device, is using a disposable email, and is suddenly creating accounts at 3am from a different country, I want to see those things individually and decide what to do with them. That's what Kaidn does. I'm especially interested in hearing from people running rewards, affiliate, gaming, SaaS, or other products where users can extract something valuable for free. What are you seeing in the wild? What's the fraud pattern that keeps coming back?
