The scammer is using a Game Flip logo picture and his/her name is “sell confirmation”.
Look at a message he sent to the user Dana Brooks:
" Sell Confirmation
Your code has been purchased! We are having problems with the automatic delivery, please give the code to the email that your buyer gave us [firstname.lastname@example.org] once you deliver the code the buyer will confirm the purchase and your money will be credited in the wallet. Order- #CT10ES2233".

Fortunately Dana did not fell for it.
