Craigslist car for sale scams. They want ebay cards

Hello folks, I’m new here but not new to the scammer revolts channel. I’ve been contacting them through craiglist. It’s the same story every time, “My husband died so I want the car gone”, “I moved away”, “I’m in the military”, etc. They reply with a fake ebay listing that is just a pdf file that looks like an ebay listing. They want payment via ebay cards. They give you an ebay “customer support” number to call to purchase the car.

This probably isn’t news here, but what should I do with the phone numbers that they give me? I have been giving them fake info through the fake address generator. What else can i do to ruin their day?
