Related. I listed something for sale on Craigslist recently and got a bunch of messages right away that asked obvious questions that were in the listing. One suggested that his wife pick it up, and can I take Zelle? Went silent when I said cash only.
But the most interesting scammer said: "for my safety, can I send you a 6-digit number, and you confirm it, so I know the listing is not fake?" I say yes, unsure what the scam was going to be, but sure it was a scam. Moments later I got an SMS from Google Voice asking me to verify my phone number. Mofo tried to steal my number, presumably to use it to scam other people. I was pissed and impressed.
