I'm trying to ruin a scammer's day (fake check scam). I have his phone number. I am able to call (and record) and text him. He is also willing to mail items to my house. What can I do to find out more about them using social engineering or through service providers? How might I be able to build a case against him, or scare or stop him from continuing scamming people?
I know I can call the FCC to report it, but I feel like that won't do anything. I also understand that I likely wont be able to get very far in following his trail.
