I don’t know if art scammers have started using real artist names or it’s just a coincidence, but there is a scammer currently using the name Crystal Moll and there is an artist with the name of Crystal Moll. They’re two different people; One is a scammer, the other is an artist.
The name or email of the scammer isn’t really that important as they just reuse the same story again and again. Just ask them to pay with Escrow.com or Paypal.com and you won’t hear back from them as their scam doesn’t work with these forms of payment.
The real Crystal Moll’s website can be found here.
