Gavin Volk and/or Corina Volk Airline Miles for Bitcoin!! Internet
Exactly the same scam as provided by an earlier poster. Contacted this individual via WhatsApp (the only contact information provided on Craigslist) and requested information on purchasing airline miles. He responded almost immediately and provided various screenshots of mileage accounts purportedly belonging to he and his wife.
(Cover story: His wife was ill and they would no longer be traveling due to her illness.) Offered to sell me miles at $8 USD per 1000 miles. When pressed for payment method he advised that he would only accept Bitcoin as a payment method.
Stay away!
