As everybody know WU transfer check system will only show you limited infos. about the status of a transfer. That's why the lbc dispute team will get tricked by this.
This is how a real scenario will happen!
First step:
Scammer will find a low feedback user that accept WU as payment and start lbc normal trade with him.
Second step:
Scammer will go and pay the money by WU to the seller but when he send the payment, send only $50. Once WU give him the MTCN he will get a blank copy of a transfer receipt and complete it using real details and real MTCN obtained from WU but change amount to real amount he has to send to the seller.
Step three:
Scammer mark payment as complete and send payment details to seller through lbc chat system. Scammer wait 5 - 10 minutes and cancel the WU transfer. The status of the wu transfer will change to picked-up.
Step four:
Start dispute. Once scammer will cancel the transfer will ask the seller for bitcoin since the seller has picked up the money.
Seller will deny. Then scammer start dispute with him on lbc.Step five:
Get the btc. Scammer will provide lbc with all the details they ask and the scammer will get btc 100%. LBC dispute team can't check for real what happens to the transfer and based on scammer evidence (WU receipt and transfer check as picked-up on wu.com) the scammer have sent the money and seller has picked up the money!
