An anonymous scammer can cook up any screenshot or pdf. Maybe when lightning comes to Bisq 2 I will consider using it.
Nobody said arbitraging is an easy job. Still, I don't see any better alternative to protect sellers somewhat from triangulation attacks.
By the way, the scammer doesn't know nor would be able to guess the bank account number that sent the fiat transfer.

Why not? He can request the other scammed party to send him proof of payment.

Fortunately I never had to go to arbitration so far, so I don't know for sure, but I see no reason why the arbiter would forward each parties submissions to each other.
That would defeat the point of catching scammers.

No, I mean the third person scammed in the triangle. The one who paid for protein powder in our case. The scammer can submit his proof of payment as his own.
reply
You're right. But he can't KYC himself to the arbiter when he is asked for proof of ownership of that bank account. Unless he manages to trick the protein powder buyer into giving him a scan of his national ID card or something.
